Custom Diffractive Optical Element Applications
Highly customized laser projected patterns in any color meeting detailed optical specifications at any working distance.
The Challenge
Many laser systems require a diffractive optical element (DOE) to project unique laser patterns for human and/or machine vision applications. Some desired patterns can be generated with off-the-shelf DOEs, while others require a custom DOE specifically designed to meet that customers’ unique optical requirements.
Our Solution
By leveraging our extensive experience collaborating with top-tier DOE manufacturers, DLC successfully designs and manufactures unique laser solutions for Custom Diffractive Optical Element Applications.
