The laser is usually fixed permanently to the side of the table and emits light towards a pair of movable mirrors so that every point of the table surface can be swept by the laser. At the point of engraving, the laser beam is focused through a lens at the engraving surface, allowing very precise and intricate patterns to be traced out.
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
The accuracy of laser trackers is of the order of 0.025 mm over a distance of several metres. [1] Some examples of laser tracker applications are to align aircraft wings during assembly [2] and to align large machine tools. [3] To take measurements the technician first sets up a laser tracker on a tripod with an unobstructed view of the object ...

A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, [1] leaving an edge with a high-quality surface finish. [2]
The lens fungus [2] does not feed on the glass itself, but on materials that were used in the manufacture [3] of the optics and/or that adhere to it (leather, paint, wood, putty, adhesives, fibers). Lens surfaces can be attacked if organic material has deposited on them, [4] such as fingerprints or vapors from plastics or grease. The fungus can ...
An early Xerox optical mouse chip, before the development of the inverted packaging design of Williams and Cherry. The first two optical mice, first demonstrated by two independent inventors in December 1980, had different basic designs: [1] [2] [3] One of these, invented by Steve Kirsch of MIT and Mouse Systems Corporation, [4] [5] used an infrared LED and a four-quadrant infrared sensor to ...
