Laser Diode Micro Modules [LDMM] – Copper

Request a quoteContact Us

Laser Diode Micro-Modules (LDMM’s) address the need for a simple, robust, reliable, and cost-effective platform on which to mount, provide heat sinking abilities, collimate, and power semiconductor laser diodes. The use of laser diodes in scores of applications has become ubiquitous, and our new products make mounting, collimating, heatsinking, and providing power leads for such applications easier than ever.

This product is currently out of stock and unavailable.


APS Copper LDMM is designed for diodes up to 2.0W

Any diode with output power up to 2.0W that is mounted in a 5.6, or 9.0 mm TO Can package can be mounted and collimated using this LDMM-Cu. For a list of compatible diodes that we offer, please visit Low Power Visible Laser Diodes (<1.0W) and High Power Visible Laser Diodes (1-2W)

Product Description

The LDMM comprises an nickel-plated copper body, a rear diode plate that is used to secure the diode into the body and provide heatsinking, and a square printed-circuit board that is mounted directly adjacent to the diode plate to which leads are soldered. The body contains a standard M9x0.5mm threaded cylindrical hole accessed from the front (output) face of the module, that is used to provide mounting for and the axial adjustment of the collimation lens. The LDMM also has two threaded mounting holes on the bottom face of the module for mounting on a heat sink, and four threaded mounting holes on the output face for the same purpose.

Our LDMM’s can be used for stand-alone applications, or can be easily integrated into customer devices. For example a stand alone LDMM can be used in the laboratory to provide an alignment laser for a wide variety of applications and in the wavelength range from 375-2000 nm. Our modules may also be used as educational tools, to teach students about the use of laser diodes, how they are connected and driven electrically, how to collimate the diode output, and how to provide heatsinking. Modules can be provided that are eye-safe and CDRH compliant, making their use as educational tools easy. Commercial, military, and medical and bio-medical applications abound.
