Frequency-modulated, lidar-based length and thickness metrology systems
When manufacturing optics, confirming that they meet specifications is critical. Testing can cause damage to the surfaces in accurate measurements of distance and thickness, and not all optics are testable with non-contact measurement techniques.
While thickness measurement methods tend to use contact systems that damage the lens and length metrology techniques use methods that have problems with surfaces that diffuse the light, Bridger Photonics provides a solution for both thickness and length applications with a Frequency Modulated Continuous Wave (FMCW) Light Detection and Ranging (LiDAR) technique. Without contact with the optic, Bridger Photonics can measure lengths of up to 2 m
and thicknesses of up to 60 mm with 1 μm precision.
The FMCW LiDAR Metrology Systems provide additional benefits including three dimensional (3D) mapping with the precision and accuracy needed in laser materials processing applications and optics manufacturing.
