Hi, I'm doing a science project and I need to show how light bends. In my project, I am using a parabolic dish (a directTV satellite dish with a shiny reflective finish) to concentrate sunlight at the receiver. But, before the light gets to the receiver (the focal point), I want to re-bend the light (diverge) into parallel light again. I need to order a lens but I don't want to waste my money buying the wrong lens. My gut tells me I need a plano-convex lens but my brain says to ask for help. Can someone help me understand what lens I should use and why?
You can use a concave lens located between the dish and the focal point (to partially diverge the converging rays to parallel) or a convex lens located beyond the focal point (to partially converge the diverging rays to parallel).
You'll have to adjust the location of the lens to get good parallelism, and there may be a problem getting the entire output of the dish to fit into the lens circle.
Ordering a lens sounds potentially expensive. If you have a local store that sells office equipment or secretarial supplies you might find a fairly cheap magnifier (convex lens) of decent size there. However, if you decide on a concave lens you'll probably have to look elsewhere.

John H. Stanfield II, the leading contemporary Black sociologist of knowledge, distills decades of his research and thinking in a set of articles—some original to the volume, others from fugitive sources—that address race in the formation of epistemologies, theories, and methodologies in social science. Stanfield’s contributions to the discipline, such as the adoption of restorative justice as an anti-racism solution in multiracial societies and the development of African diasporic sociological reasoning, are highlighted here. Ranging widely across theoretical, methodological, and substantive topics, Stanfield creates a reflective sociology viewed through an African diasporic lens that enriches the thinking and practice of social science.

Anit reflective glasses lens coating..?
I'm getting new glasses and im getting the anti reflective lens coating on it so light doesn't show on the lens.
But im wondering if when i go on my webcam, will the light from the computer screen reflect still or no, since i'll have the coating on them?
No it will not. I have had anti reflective and even though some things can reflect (if your sitting by a window and looking in a mirror you can see the green outline of the blinds on your lenses, it tints green from the coating). The computer screen is not going to cause glare on your glasses.

High Power Red Laser Diodes Guys i need your help so bad. Can you try to figure out the ohms of resistor i need?
I made a laser burner, its working but for a minute, the resistor burned out.
I have a 660nm-200mW laser diode ( red)
High output power: 350mW(pulse)
High efficiency: 0.95W/A (typ.)
Visible light: 660nm (typ.)
im using a 9.6v as operating voltage
But i dont know how to figure out the ohms resistor i need and the operating current.
it says something like "standard pulse light output of 350mW" and or something like "highly and reliable high-power operation at 75 }c.
is the 350mW the operating current, or the 75}c?
and what ohms of resistor do i need to use. because i tried a 7.5 ohm resistor, and it works, but suddenly a couple of tries, it burned out.
The supplier should be able to tell you the operating current and any other infortmation you require.
And no, 350mW is not a current it is power, the pulsed (intermittent) power which the diode can produce.
Without knowing the recommended operating current it is impossible to calculate the value of the necessary resistor.
High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

Okay, just about everyone has a red laser pointer. Heck, we even sell a fine one here at ThinkGeek. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go. This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer. Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm. Features of this unit include: Very bright green laser at 532 nm wavelength Output power of Range of approximately 9,000 ft (2600 m) in darkness 1.1 mm beam diameter at source Momentary push button switch Solid, heavy duty construction Constant wave output (as opposed to pulse output) Takes 2 "AAA" batteries (not included) Can be used for skypointing, projection on low clouds, signaling, highlighting potential explosives Dimensions: 5.6" x .5" dia 90-day warranty Available in Black or Silver color Interested in quantity discounts or custom logo imprinting? More info here. Warning: Green lasers are very powerful. Pointing at aircraft may land you in jail. Without a Monopoly card to get you back out. Use it wisely.
Revised and fully up-dated, the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III-V semiconductors. Elementary properties such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III-V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises, solutions, and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering, applied physics, and materials science.
Many people have a red laser pointer and some really cool people have the green laser pointer. But very few people have them both built into a single unit. Being the cutting edge geek that you are, we know you'll choose this dual output beauty. Why would you want to be like everybody else? The first laser pointer that projects a brilliant GREEN beam from one end and also a high-power RED beam. The GREEN beam is just as bright as other green pointers, range up to 2 miles in darkness, wavelength 532 nm. The green laser beam (not just the dot) is visible at night. The RED beam is the most powerful red laser allowed by the FDA, range 4000 ft in darkness.

Lighting is essential to modern society but it accounts for nearly 20 of the electrical energy usage. Thus efforts to increase the conversion efficiencies of light sources are attracting more and more attention. Potential high efficiency light sources are fluorescent lamps or lightemitting diodes (LEDs). Modern LEDs show internal quantum efficiencies of virtually 100 . However, in the case of standard LEDs most of this light is trapped inside the device because of total internal reflection at the interface semiconductorair. Several methods have been developed in order to increase the extraction efficiency. This can be done either by optimizing the device geometry in order to increase the escape cone or by incorporating a resonant structure in order to force the internal emission into the existing escape cone. The latter approach is called microcavity LED (MCLED) or resonant cavity LED (RCLED) and is presented in detail in this work. Novel concepts to further increase the external quantum efficiency are discussed and experimental results are presented.

473nm Blue Laser Beam – The Blue Laser Pointer seen worldwide
A blue laser beam is generated at a frequency of 473nm laser light with a crystal advanced. Since her release, broad scale, blue laser diodes has seen persistent jumps designs, as well as sales offices worldwide. What started as a bulky box 473nm laser device has evolved over time to the present day blue laser pointers are hundreds, even thousands of different varieties. However, there is some concern about the purchase of low costblue laser pointer. This is because the diode is relatively new to the market and many crystal laser technicians are familiar with the work on blue lasers Its not surprising that it took years after the creation of 473nm blue laser in front of several held hand laser pointers have been made available.laser pointer green
Laser pointer hobbyists and professionals are accustomed to the site of a powerful green laser or red laser, so that ifShuji Nakamura for the first time its blue LED to publish an open market, there has been a huge influx of large firms to capture over time. Obviously, if the word beautiful as a blue laser beam scale may now be produced in general, According To a 473nm laser pointer to the growing demand and began to grow. Finally, in 2005, launched the online market to see, many retailers are trying to promote and advertise their new laser blue laser designed handheld.laser pointer green
ThoughListed were initially a bit 'sluggish. The blue laser diode laptop was completely "baby" and many designers have trouble creating high-quality laser pointer blue hand, it would be able to maintain consistent performance in some reality. The problem is that most producers should exercise was a drawing of the crystal blue laser is much more difficult, a convenient solid-state laser pointers than their predecessors, green or red. For the firstModels or generations, most of the 473 nm blue laser was pretty bad. Many users have reported that the diodes burn out, or the radius would then diverge, or not very visible, or even start a violet beam to produce at lower temperatures. The outlook for the beginning of blue laser pointer should not be very bright. READ MORE http://www.laserpointergreen.goodarticlesite.com/473nm-blue-laser-beam-the-blue-laser-pointer-seen-worldwide/
Solar Array Diode Have I destroyed my solar panels?
I had a little confusion today when connecting solar panels in to my inverter. Basicly I lost my cable markings and tried tracing the cables the best I could. I had two strings of pannels. When I connected my cables together (for my Isc short circuit current test) I Got some really low readings (0.2a) Later on I discovered that I had connected my cables incorrectly. I have a feeling that I connected both the negative ends together and both the positive ends together. Would this destroy the panels? If so, would I have destroyed the diode inside each panel or the whole array? Please help, Im sweating on this one! D
It's unlikely that any lasting damage has occurred.
I've seen panels improperly installed in a loop, and left for a day. Nothing happened. A panel can be short circuited indefinitely, and nothing happens. Theoretically, there may be a fuse inside each panel that would blow on extreme overcurrent, but in practice, you would really have to try hard to make it blow.
Just disconnect the panels and wire them properly; things will be fine.
Whether the sun is out in full force or the sky is overcast, you can depend on the rugged reliability of the Brunton Solaris Foldable Solar Array. Using advanced light-gathering technology that works in all conditions and weatherproof construction for protective peace of mind, this durable solar panel is easy to use and transport.
Representing the next generation of solar panel technology, the Brunton Solaris 26 Solar Array maximizes performance while taking up virtually no space at all. The unit's multi-section design folds up into a compact footprint that's just a bit larger than a DVD case, while still delivering an impressive 26 watts of power, more than enough to charge a laptop or digital video camera or power a satellite or cell phone. In addition, the unit's high-performance CIGS solar cells--the most efficient thin-film solar technology available--are extremely reliable, with a design that instinctively converts incident sunlight into an electrical current, even in low-light conditions. The combined functions make this an ideal panel for camping trips, hikes, power outages, and other occasions when it helps to have a portable power source on hand. The Solaris 26, which measures 21.5 by 37.5 inches when open and 11 by 8.5 inches when folded, includes a battery clamp cable for charging car batteries, along with vehicle outlet and multi-linking cables. It's also backed by a one-year warranty.

How Can I Build A Cheap Solar Panel To Power My Home
3 Solar Panel Battery Wiring Samples
Depending on your needs, you may have to use some or all of the following tools and materials: solar panel(s), 12V "car battery" (deep-cycle lead-acid battery), diodes, insulated wire, wire cutters, pliers, wrenches, and screwdrivers.
Let's imagine that you bought a solar panel with a certain maximum output voltage and certain amperage. Now you need to hook it up to a battery. All batteries have specific amp ratings. You will need to determine how many panels will charge your battery adequately.
Once you do the calculations, you will need to either connect the panels straight to the battery, or use a diode in between. It is better to use a diode between your cell(s) and the battery, especially in the systems larger than 12V. If you do not use a diode, your battery may discharge at night. What diode will you need to use? You need a diode of the same (or more) amps as your panel.
3 Solar Panel Battery Wiring Samples
1. Connecting Solar Panel and Battery (Without a Diode):
- Panel's "plus" to battery's "plus". - Panel’s "minus" to battery's "minus".
2. Connecting Several Panels in Parallel (for more power), and then to a Battery:
- Each panel's "plus" to other panel's "plus", and so on. - Each panel's "minus" to other panel's "minus", and so on. - The last panel's wires to the battery (follow the two steps from the 1st example).
To calculate the total amperage of your array, add the amp outputs together. Voltage stays the same.
3. Connecting Solar Panel, Diode, and Battery:
- Panel's "plus" to diode's "in". - Diode's "out" (the end with a black or silvered line) to battery's "plus". - Panel's "minus" to battery's "minus".
Notes about Solar Panel Battery Wiring:
1. Remember, going below the battery's voltage will not charge the battery fully.
2. Note that a diode will decrease the voltage.
3. Some lead-acid batteries may need a regulator providing certain voltage in order to leave them on forever, without an overcharge damaging the battery. Otherwise you will need to switch your battery off manually when it's fully charged.
When your solar panel starts to produce energy, this energy can either dissipate or be diverted into a battery for your future needs. Many people choose to use systems with batteries, which allow for a power backup. You can also use batteries for your outdoor equipment (golf carts, tractors, motor boats) and various portable devices (laptops, cameras, cell phones, electric fans).
However, remember that you don't necessarily need to use batteries in your home system. You can have the energy generated by the panels fed into the grid, thus eliminating the need for any batteries.

A nonlinear relation between current and voltage for schottky resonant tunneling diode is used. A general form of equation similar to VanDer Pol equation is obtained. A Resonant tunneling diode(RTD) has a negative differential resistance that means when the voltage increases the current decreases. This property is very useful for oscillators manufacture. Nonlinear transmission lines is considered to show that it canbe used in oscillators and to show that it can reshape the sinusoidal signals to othershapes by using OrCad and mathematica programming.
