What Is Random Pattern Laser Module?

Dec 31, 2020

With the vigorous development of 3D scanning, machine vision, face recognition, and industrial automation industries, machine vision lasers are becoming more and more popular in the market. In addition to uniform line lasers with fine stripes, uniform power distribution, and edge definition, random lattice lasers are gradually being explored and applied.


3D 

Random dot matrix laser module is a laser module that can directly output random dot pattern. It is generally composed of semiconductor laser/VCSEL laser and optical module with random dot matrix DOE. The working distance is adjustable and the power is 1mW~300mW. Random lattice laser modules are also called random lattice modules, speckle laser modules, random lattice structured light modules, and portable random lattice modules. It can be used in fields such as face recognition and three-dimensional scanning.

As a professional laser module manufacturer, Elite can provide Random Pattern laser module, the optimum wavelength range is 810-850nm, the design wavelength is 830nm. The output power can be customized. The wavelength of the laser should match the design wavelength of the DOE, otherwise the large Angle pattern resulting from its symmetry will be affected by geometric distortion.
