Laser diode collimators

The Optoelectronics company, a global supplier and manufacturer of innovative optoelectronic components including Opnext laser diodes and Panasonic lenses, has introduced a range of laser diode collimators with high alignment accuracy specifically aimed at OEMs and system integrators using laser based technology in their products.

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 numerical aperture collimating lens. By adjusting the distance between the laser diode and the collimating lens, the factory-fixed beam can be set for a collimated or focused output to meet customer requirements.

The laser diode collimators from the Optoelectronics Company measure 6mm in diameter and 8mm in length. They are available in standard lasing wavelengths from 635 to 852nm, with standard output powers from 0.9 to 75mW although customised versions can be manufactured to order.  They have an elliptical output beam with a collimated diameter of only 2.5 x 2mm which is bore-sighted for greater precision.  The output beam can be collimated or focused as necessary.
