​Product Families

Coherent’s world-renowned structured light lasers transform the familiar laser dot into a wide range of structured light patterns including single and multiple laser lines with uniformity down to +/- 1% CV. Straight laser lines are projected by allowing one dimension of light to fan out while maintaining tight control over the other, resulting in a uniform sheet-of-light.

Evenness of the illumination patterns distinguish Coherent’s family of structured light lasers from conventional lasers. Coherent’s structured light lasers incorporate a patented optical laser line generator that eliminates Gaussian distribution of the light, resulting in the most uniform laser lines on the market. The design provides superior quality light patterns while avoiding the intricacies of installation alignment and detector calibration.
