These materials are called semiconductors. http://www.azooptics.com/details.asp?ArticleID=147 The mouse is an input tool designed to control objects on the display screen. The mouse senses these movements and is transmitted to the computer in order for it to react in an appropriate manner. http://www.azooptics.com/details.asp?ArticleID=146 The research of the Nanoscale Electronics and Photonics Group of Prof. Brongersma at Stanford University is focused on the fabrication and characterization of nanometer-sized electronic and optical devices. http://www.azooptics.com/details.asp?ArticleID=145 Femtosecond lasers are a type of laser that discharges optical pulses in femtoseconds. Femtosecond lasers belong to a class of ultrashort pulse lasers or ultrafast lasers. Passive mode locking technologies has been employed for the generation of short pulses. http://www.azooptics.com/details.asp?ArticleID=144 LIDAR, which stands for light detection and ranging, is an instrument that uses an intense laser light transmitted at an object and detecting the laser light reflected by the object. http://www.azooptics.com/details.asp?ArticleID=143 Binoculars can be considered as having two telescopes which are exactly the same placed next to each other and accurately pointing at the same direction. Binoculars allow the user to use both eyes when looking at distant objects. http://www.azooptics.com/details.asp?ArticleID=142 Magnifying glass is used to look at tiny objects or fine print and they are available in various forms. http://www.azooptics.com/details.asp?ArticleID=141 Light is used by optical tweezers to control microscopic objects the size of a single atom. A focused laser beam generates radiation pressure which is capable of trapping small particles. http://www.azooptics.com/details.asp?ArticleID=140
