The special pattern structured light DOE has a variety of pattern shapes, including square, hexagon, scanning frame, alignment frame, concentric circles and other standard products, and the design wavelength is from 532nm to 780nm. The special pattern DOE is designed according to the principle of diffractive optics. Diffractive optics can design unlimited possible output light patterns for specific incident lasers. Therefore, we can also customize patterns with various wavelengths, various patterns and various angles. Welcome consult.

As the demand for structured light in various industries continues to grow, Laserland has independently developed 20 or 30 standard glass material structured light lenses and diffraction homogenizers to meet market needs.
Structured light lenses are characterized by relatively cheap price and short delivery time. The pattern of structured light includes single line, multi-line, grid, cross line, alignment frame and random speckle structured light, as well as keyboard pattern and some customized patterns.
