Special Patterns
Our diffractive optical elements (DOEs) transform a standard laser beam into precisely defined patterns—including multi-line arrays, grids, viewfinders, circles, crosshairs, and dot matrices—enabling advanced structured light applications. Designed for wavelengths from 450 nm to 980 nm, these elements provide consistent pattern performance across broad spectral ranges. Ideal for machine vision, 3D scanning, alignment systems, and laser aiming solutions, our DOEs deliver reliable optical precision in a compact, easy-to-integrate format.
