Press Release: Cobra OEM OCT Spectrometer

Wasatch Photonics introduces compact, lightweight OCT spectrometer for integration into OEM imaging systems

MORRISVILLE, N.C. – March 4, 2022 – Wasatch Photonics has expanded its Cobra OCT spectrometer product line with a new OCT spectrometer designed specifically for ease of integration by OEMs into OCT imaging systems. The Cobra OEM is a small size and low weight spectrometer optimized for 800 nm spectral domain OCT (SD-OCT) imaging, and is based on a configurable optomechanical bench engineered for volume manufacturing. It builds on the company’s existing line of Cobra OCT spectrometers, expanding their application in turnkey systems for ophthalmology and eye surgery, materials processing and laser welding, and industrial inspection of surface topology and microelectronics packaging.

The Cobra OEM OCT spectrometer is offered in multiple bandwidths centered at 840 nm, each matched to commercially available superluminescent diode (SLD) light sources, thereby facilitating compact, cost-effective OCT imaging in volume. Weighing only 0.7 kg, the spectrometer can be read at speeds up to 250 kHz using Wasatch Photonics’ rapid access software development kits for C++, C#, LabView, and MatLab. The Cobra OEM uses a high efficiency optical design optimized for high sensitivity and low roll-off, delivering comparable performance to the company’s flagship Cobra-S OCT spectrometer to enable high-quality imaging in volume. It leverages Wasatch Photonics’s patented volume phase holographic (VPH) grating technology, volume production of compact OEM spectrometer engines, and vertically integrated manufacturing. It offers system developers an opportunity to accelerate their product design and launch by working with an experienced OEM engine provider, reducing risk and development cost and speeding ramp to volume production.

“We developed the Cobra OEM OCT spectrometer in direct response to a need from our industrial OCT customers for a very compact, drop-in OCT spectrometer that would allow them to capture high quality images without adding undue size or weight to their systems,” says Dr. David Creasey, CEO. “High efficiency compact optical spectrometer design is one of our core compentencies,  and when paired with our industry-leading, patented OCT gratings, we were able to create a spectrometer for SD-OCT that delivers low roll-off — comparable to a research-grade spectrometer but in a much smaller footprint, and highly manufacturable in volume.”
