Optical Construction

Suggestions for quality optical mouse?

Nothing is more frustrating than a poor quality computer mouse. Cutting off and on due to poor quality wiring, failing scroll wheel/button, cheap construction. I'm looking for a mouse thats going to last a while and is also decent for gaming. I dont work in a traditional work space (desk, mousepad, etc) so I need something that can take a bit of a beating. Not looking to spend more than $25 bucks tho. Suggestions welcome.

At my work I use a Lenovo optical mouse and it does a good job. They range in price between 22 and 50 dollars depending on where you get it at. This mouse is used throughout the entire company and believe me they last against a beating.

Optical AddDrop Multiplexer $66.91 High Quality Content by WIKIPEDIA articles An optical adddrop multiplexer (OADM) is a device used in wavelengthdivision multiplexing systems for multiplexing and routing different channels of light into or out of a single mode fiber (SMF). This is a type of optical node, which is generally used for the construction of optical telecommunications networks. Add and drop here refer to the capability of the device to add one or more new wavelength channels to an existing multiwavelength WDM signal, and/or to drop (remove) one or more channels, passing those signals to another network path. An OADM may be considered to be a specific type of optical crossconnect. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Optical Methods for Solid Mechanics (Paperback) $265.27 Unique within the field for being written in a tutorial style, this textbook adopts a step-by-step approach to the background needed for understanding a wide range of full-field optical measurement techniques in solid mechanics.This method familiarizes readers with the essentials of imaging and full-field optical measurement techniques, helping them to identify the appropriate techniques and in assessing measurement systems. In addition, readers learn the appropriate rules of thumb as a guide to better experimental performance from the applied techniques.Rather than presenting an exhaustive overview on the subject, each chapter provides a concise introduction to the concepts and principles, integrates solved problems within the text, summarizes the essence at the end, and includes unsolved problems. With its coverage of topics also relevant for industry, this text is aimed at graduate students, researchers, and engineers involved in non-destructive testing for acoustics, mechanics, medicine, diagnosis on artwork and construction, and civil engineering.

if you had a choice, would you get the sony cyber shot dsc w-300 or the sony cybershot dsc-t77?

Any experts on digital cameras? I am in the middle of deciding my camera but can't decide. The dsc-w300 got great reviews and has 13mp. the sony dsc t-77 has a higher optical zoom i believe 4x or 5x and has 10mp. Would having a higher optical zoom be better?
The optical zoom on the dsc w300 doesn't show but it does say 2x digital zoom. The focal length is 7.6mm-22.8mm (so what is the optical zoom on this one), Lens construction is 5 groups/6 elements. What does that mean? Flash Range is 8in-18 ft.

The cybershot dsc-t77 4x optical zoom: focal length is 6.18mm-24.7mm, lens construction is 10 groups/12 elements and flash range of 3in-10ft.
What is a better camera?
what would be the best buy here and worth my money.
the dsc- w300 is so much more pricier than the other.
camera experts please help me with this?

Sony W300 come with 3x optical zoom hower I would go with Sony T77.Better zoom with 3" touchscreen LCD
