Optics / Diffractive Optical Element

Diffractive Optical Element (DOE)

Lasermate Group, Inc. offers a variety of Diffractive Optical Elements (DOEs) to generate structured light using laser diode modules. With different non-random dots patterns, including multi lines, circle and dot lines, cross hair, concentric patterns, squares, viewfinders and grids, and random dots patterns, the DOEs can be integrated with a simple laser dot module to create various beam patterns. They can be applied in 3D sensing and 3D mapping applications, internet of things (IOT), a variety of instruction, positioning, parallel processing, adjustment applications, machine vision, animation and structured light projection. Our DOEs are available in PET, PMMA and glass substrate materials. Other diameter sizes may be available upon request.
