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 (NA) 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 only 6mm in diameter and 8mm in length. “Collimated laser diodes have no drive electronics, resulting in a smaller and more affordable laser source for OEMs and system integrators who have separate or remote drive electronics and just need a laser device that can be designed into a tight space“, explained Tony Pope, M.D., the Optoelectronics Company Ltd.
They are available in standard lasing wavelengths from 635nm to 852nm with standard output powers from 0.9mW 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.
The Optoelectronics Company’s collimated laser diodes offer power and superior beam quality with divergence angles as low as 0.6 mrad. They provide an ideal beam source for system integration and offer the simplest, easiest and most economical way to deliver laser light to a variety of OEM applications including industrial and automotive alignment, medical alignment, positioning and sensing, machine vision, industrial instrumentation and targeting.
Custom lasing wavelengths and power options are available. Both standard and custom configurations provide OEMs, end-users and systems integrators with complete, cost-effective laser solutions.
