Pattern Generators / Diffractive Optical Elements for Laser Diodes

TOPAG offers different diffractive optical elements (DOE) to generate structured light using laser diode modules. You can choose different patterns like multi lines, dot lines, crosshair, circles, dot matrix and random patterns. This DOEs can be added to any of our dot laser modules. Please request for availability of DOEs and their fan angle. Furthermore TOPAG offers the possibility to produce customized DOEs/patterns and fan angles.
