The 7-sources Optical Matricial Head (OMH-7s) of BreizhTechTM has been designed for an easy and precise X-Y adjustment of its laser beams. It enables, among other things, to generate a compact and colinear multibeam laser group from several sources distributed radially. These 7 sources are laser diodes or laser diodes modules emitting from the near ultraviolet to the near infrared (300 nm to 2000 nm, or more upon request), optical powers can be high (Class 1 to 4). The OMH provides a high-precision adjustment function thanks to a patented 3-points tuning technology using high-precision screws. The average precision is 10 mrad/screw turn/axis. The OMH is equipped with an axial M26x1 thread, allowing the addition of an optical device such as a beam reducer or expander.
Note that the OMH may be equipped with a capacity from 4 sources up to 128 sources for high end applications simply by stacking the different stages.
Each laser diode or laser diode module is integrated in a patented device, called Optical Source Module (OSM), allowing its alignment and its temperature control (heat dissipation by copper specific matrice and integrated fans). The compact design of the OMH-7s and its anodized aluminium body provide a great hardiness (resistance to wearing, corrosion and heat). An internal system of laser beams concentration (based on a central pyramid equipped with High Performance aluminium mirrors) allows high reflection coefficient (R = 98 %), with a possible very high optical power (thanks to the high damage threshold of the mirrors).
The OMH-7s is customisable upon request: it can be sold as a stand-alone sub-system or integrating laser diodes (with standard or specific electronic control upon request) or laser diodes modules. The OSM-7s offers an exceptionnal modularity in terms of choice of integrable laser diodes / laser diodes modules in the near ultraviolet, blue, red, and the near infrared. Standard electronics offer an ultra-fast laser control for telecom applications. Electronics can also be specified upon request.
