Multi-Line Laser Module Zero-Order Suppression
A Shanghai equipment customer saw clear zero-order spots and stray-light interference during multi-line laser module testing. The interference reduced clear separation between lines, made camera recognition harder, and degraded 3D scanning and structured-light imaging performance.

for Real Imaging Challenges
After reviewing the customer’s working distance, line count, fan angle, equipment structure, and camera recognition method, the Desheng Laser optics team refined the optical design. Targeted optics and test validation helped reduce zero-order interference and deliver clearer, cleaner, more stable multi-line output.


For Multiple Structured-Light Applications
This solution suits handheld 3D scanners, machine vision, industrial inspection, and structured-light applications.
