Cobra OEM OCT Spectrometer

Robust design for OEM integration

We’ve designed the Cobra OEM spectrometer to be our most compact, lightweight OCT spectrometer yet, optimized specifically for the needs of OEMs. This robust OCT spectrometer module delivers comparable performance to our signature Cobra-S OCT spectrometer and is offered in multiple bandwidths centered at 840 nm for imaging depths up to 4 mm in air, matching available SLD sources for cost-effective OCT imaging in volume.

As a spectroscopy company, we understand the nuances of optical design needed to optimize sensitivity and SNR in a small footprint without compromising manufacturability. The result? A high performance yet cost-effective OEM spectrometer for SD-OCT, with high resolution and multiple options for imaging depth. When designing your next system, we’ll help you get the quality images you need to make decisions, quickly.

Cobra OEM spectrometers can be used for OCT imaging in the 750-930 nm range in medical and industrial OEM solutions. Let our expert team put together a configuration that is right for your application.

Cobra OEM part numbers are of the format CO800S-[CWL]/[BW]-[kHz]-[camera][pixels], where the camera is represented by a 2-letter code, and 2K denotes 2048 pixels. Imaging depth stated is the theoretical value, calculated in air. Custom bandwidths are available upon request.

Like our flagship Cobra-S 800, the Cobra OEM OCT spectrometer offers superior roll-off performance, as can be seen in this comparison of signal with imaging depth. With less roll-off, much deeper structures can be imaged clearly than is expected of typical 800 nm imaging.
