HOTECH’s Advanced CT Laser Collimator uses a flat mirror at the eyepiece location, a target placed in front of the telescope, and three lasers to align your Schmidt-Cassegrain telescope.

Aspheric Lenses are particularly prevalent within laser diode-to-fibre coupling applications for this distinct advantage. Here at Knight Optical, we have vast experience of working with engineers on ...

Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. They consist of a laser diode, a laser diode holder, a collimating lens holder and a high ...

Designed to collimate or focus light exiting an optical fiber to a desired beam diameter, the collimators could be used with laser diodes, photodiodes, acoustic-optic modulators and other fiber ...

Nature Materials – Designer spoof surface plasmon structures collimate terahertz laser beams Scientists from Harvard University and the University of Leeds have demonstrated a new terahertz (THz) ...

Also presented are analytic expressions for the amount of field-dependent astigmatism due to miscollimation. The technique is robust enough to collimate telescopes with fixed astigmatism in the ...
