Introduction Spectrophotometer is an optical instrument that measures and shows how much light energy is transmitted by a substance in solution at different wavelengths of radiant energy. Light passes into a monochromator where only a very narrow range of wavelengths can pass through. From there‚ light is transmitted through a sample solution‚ and on to a phototube where the light energy is converted to an electric current that is registered on a meter. To measure the amount of light absorbed

Optical Distortion‚ Inc (ODI) is a company that has developed special contact lenses to harmful impact the eyesight of egg-laying chickens. The reduced vision from the contact lenses helps preserve the life of chickens‚ increase the productivity of egg laying and reduce costs for farmers using the lenses for their flocks. At the end of 1974‚ ODI’s owners and management were finalizing a strategic marketing plan to introduce the lenses commercially early in 1975 and work towards nationwide penetration

Optical Properties of Quasicrystals: Negative Refraction Quasicrystals‚ or crystals that display the unusual property of non-periodicity (while remaining ordered)‚ were discovered in the 1980s by Dan Shechtman. A highly controversial topic‚ Shechtman did not produce a paper describing them for over two years after their discovery. However‚ within the past 30 years‚ the scientific community has come to accept them‚ reproduce them for study‚ and even award Dan Shechtman with a Nobel Prize for their

The Optical Time Domain Reflectometer (OTDR) Introduction In fiber optic networks‚ OTDR (Optical Time Domain Reflectometer) is an opto-electronic instrument used to characterize an optical fiber. Unlike power meters OTDR does not measure loss‚ but instead implies it by looking at the backscatter signature of the fiber. Generally‚ OTDR are used to determine the loss of any part of a system‚ the length of the fiber and the distance between any points of interest. Most of the light which is

Case Analysis: Optical Fiber Corporation Introduction Optical Fiber Corporation (OFC) is a financially successful‚ albeit relatively small manufacturer of multimode optical fibers. The company was founded in 1990. The founders were able to enter the market largely on the basis of acquiring patent licenses from larger optical fiber firms. These licenses restricted competition between the entities and provided OFC with instant access to optical fiber technology. In return‚ OFC’s customer

Electronics- Fall 2012 Wired Optical Mouse Dissection For the “Take it Apart and Figure It Out” Project‚ Team Arsenic was given a wired optical mouse. The mouse brand was Onn‚ produced by Blue Trace Technology and sold by Wal-Mart. During the in-class part‚ we obtained a basic understanding of the workings of the mouse‚ but‚ to completely understand the operation of the mouse‚ we had to research the various parts individually since no blueprint for the mouse exists. After understanding the

This river is as much a part of Oregon ’s culture as Crater Lake or Mt.

Rivers of BAngladesh The rivers of Bangladesh mark both the physiography of the nation and the life of the people. About 700 in number‚ these rivers generally flow south. The larger rivers serve as the main source of water for cultivation and as the principal arteries of commercial transportation. Rivers also provide fish‚ an important source of protein. Flooding of the rivers during the monsoon season causes enormous hardship and hinders development‚ but fresh deposits of rich silt replenish the
