Laser precision meets operational efficiency.
Bridger Photonics develops and manufactures standard and custom laser-based length metrology solutions to meet your specific measurement challenges. Our proprietary hardware systems measure absolute distances and surface separations ranging from several millimeters to many kilometers with unmatched precision and accuracy. Using a chirped frequency-modulated continuous wave (FMCW) technique, our non-contact systems measure the thickness of samples without damaging the material under test. Bridger Photonics offers accurate, repeatable, and reliable measurements to meet quality standards and improve your yield.


Custom Metrology Solutions
Designed to fit your unique metrology requirements
Industrial metrology companies often require specific high-performance laser-based length metrology components to enable their next-generation system-level product. From proof-of-principle experiments and product development to full-volume production, delivery, and support, we work to ensure your custom needs are met.
