This textbook provides senior undergraduates studying modern optics with a comprehensive account of optics and optical electronics. A large number of solved and unsolved problems are included in the book. The extensive coverage makes it valuable to postgraduates, and also to optical engineers, as a source of basic design information.The initial chapters cover the basic principles involved in the propagation of electromagnetic waves. These are followed by a description of diffraction and its application to spatial frequency filtering and holography. Laser theory and the various types of laser are covered, as well as the theory of optical waveguides, fibre optics and integrated optics. The final chapters cover electrooptics, acoustooptics, and nonlinear optical effects. Author: Ghatak, A. K./ Thyagarajan, K./ Thyagarajan, K.

Although glass was the only lens material for over 600 years, today plastic lenses used for prescription eyewear and sunglasses requiring high abrasion resistance and high quality optical properties have been developed. High index plastic lenses are a new lens category, having refractive index from 1.54 to 1.71. Recently, much interest has been shown in new high index polymeric materials. Main target is lenses with good optical performance; high refractive index, low constringence, good light transmission and UV absorption. Outstanding factors defining this performance are refractive index and chromatic aberration. This book, therefore, provides measurements of refractive index using a light source or a laser beam and computing the minimum deviation angle through a prism of the material, chromatic aberration determined by evaluating the optical performance of the material itself. It should be especially useful to professionals in industrial, educational and marketing fields, or anyone else who may be interesting in measurement techniques, properties or performance of new optical materials Author: Chandrinos, Aristidis Binding Type: Paperback Number of Pages: 136 Publication Date: 2009/03/01 Language: English Dimensions: 9.00 x 6.00 x 0.32 inches
Caution: This product is more amazing in real life than on a two dimensional website As you should well know here at ThinkGeek we are constantly striving to find tools for you, our loyal customers, to aid in your quest for World Domination. But we also want to encourage you to come up with schemes to conquer the entire Universe (and any parallel universes you might stumble across while conquering this one). And to properly conquer the known Universe, you'll need a a nice reliable star map. The Laser Stars Projector is not that map, but it sure does seem like one. And the second most important thing a Universe conqueror might do besides conquering Universes is seeming to conquer Universes. Keeps you buttered up for the real thing. Ok, carrying on then... When you turn off your lights and turn this unit on - trust us - you will be bamboozled with star rapture. That's the only way we can describe it. Everybody who has seen the Laser Stars Projector in action at the ThinkGeek headquarters has at least one 'Oh My Gods, that's Frakking brilliant!' moment. But ThinkGeek, what IS the Laser Stars Projector really? It's a unit about 10inches tall that projects a combination of green laser stars and blue (slightly ultraviolet-ish blue) clouds onto your ceiling, walls, pets, etc. Both the clouds and the stars are constantly moving and morphing, just like a proper Universe should. And there are literally thousands of green laser stars to look at. There are two ways you can adjust your Laser Stars Projector, first you can pivot the projector itself 180 degrees horizontally around the base so that you can control *where* it is projecting in your room. It can literally fill up an entire ceiling and portions of several walls at once. And the other thing you can adjust is the intensity of the blue gaseous clouds, from zero to full intensity. ThinkGeek, I'm a techie. How does it really work? The Laser Stars Projector utilizes a state of the art Diode Pumped, Solid State (DPSS) green laser combined with custom developed multiphase diffractive holographic optics, super luminous diodes and precision motors to produce the laser stars effect. The coherent light produced by the DPSS laser passes through a passive diffractive holographic optical element, which in turn passes through a circular periodicity electromechanical wheel, which is driven by a precision motor to create the soothing motion of the star field. So there. Hurry, get one before your friends do. Then plug it in, turn it on, and tune out... Features: Uses Green Laser and Holographic technology 2 built-in precision glass lenses Creates thousands of stars with or without blue cloud formations Ac Adapter Included (US Only - 120V) Unit Dimensions: 10" tall x 9" wide x 7" deep Please note: It's difficult to portray what the Laser Stars Projector projects here in images because it works best in the dark. The images tend to mute the green stars and exaggerate the blue clouds a bit. But we've tried our b...

Need help choosing what to do science project on!?
I posted this in the physics section and no one is answers. =[
I have a science project and the project is doing a powerpoint on how an optical instrument or technique works.
Here are the choices:
Camera
Movie Projector
Microscope
Refracting Telescope
Reflecting Telescope
Eye Glasses
Binoculars
Laser
Endoscopic surgery
Laser Eye Surgery
My question is which one of these things do you think is easiest or simplest to do?
Which one should I choose to do my project on?
Thanks so much!
=]
Honestly Microscope or Laser eye surgery may seem hard but there is a hell of alot of information on the internet about these, and you would probably get alot of credit cause they may look complicated but just google it and you'll get tons of information[: you'll get credit from your teacher because they seem quite interesting.
goodluck hunny[:
[do the one you feel most comfortable with] :]
