OCT Probe / Scanning Arm Solutions

Our compact, high performance OCT probe designs can be integrated into any system to expedite one of the most challenging and critical aspects of OCT system development, the sample arm. This line of OCT probes includes MEMS and galvanometer-based models that scan at 20-200 Hz, all with an onboard 2 megapixel color camera.

We’ve combined our innovative optical design with robust electronics for precise focusing, repeatable xy scanning, and high-transverse resolution at working distances >20 mm. Flexible enough for research and robust enough for industry and OEMs, they can be integrated easily with any OCT system, and go from handheld to mounted in seconds. Contact us to find the right model for your application.
