Enabling OCT with Innovative Solutions

Gratings & spectrometers for faster, clearer imaging

Optical coherence tomography is a powerful technique for non-destructive 3D imaging of tissue and materials. It is used in research, medical diagnostics, guided surgery, industrial processing, and non-destructive testing. At Wasatch Photonics, we enable those applications with innovative solutions built on our industry-leading OCT gratings. Our patented designs reduce roll-off and increase sensitivity for faster, clearer images. Whether you’re a researcher or OEM, we’ll support you with the right grating or spectrometer to quickly build a system that captures the images you need.  Contact us today!

Our patented gratings for OCT lead the market, delivering superior 1st order diffraction efficiency and low scatter for all polarizations, even at the extremes of a 100-200 nm bandwidth range. This translates into less roll-off and faster scan rates for your SD-OCT spectrometer or system, regardless of the application.

OCT Grating efficiency


The best images start with the right spectrometer, and we offer more than 30 models with speeds up to 250 kHz to find your perfect fit. Choose the center wavelength and bandwidth for the depth and resolution you need, then select the camera, speed and connection right for your application (including USB 3.0). Our proprietary low roll-off design delivers the best images possible.


We’ve developed powerful SDKs and software to help you acquire, process, and visualize data from our high-performance Cobra series spectrometers  quickly and easily, bypassing the need to sift through lengthy manuals to acquire data from the cameras most often used for OCT. Whether you need to collect images with your system or rapidly develop your own laboratory or OEM software for a spectrometer, we have the tools to speed your development.
