The Cobra-S 800 ultra high speed spectrometer heralds a new era in spectral domain OCT. Wasatch Photonics’ newest Cobra  OCT spectrometer pairs our industry-proven high throughput spectrometer design with  athermal optomechanics and the fastest camera on the market for extremely high resolution imaging at more than 2-3x the speed of conventional OCT spectrometers.

We’ve taken our compact, robust Cobra spectrometer to the next level with a revolutionary  new design and camera. Capable of line rates approaching SS-OCT, the Cobra-S offers  significantly higher speed and better roll-off than any other SD-OCT spectrometer on the  market. From bloodflow dynamics and vibrometry to imaging of dermal vasculature and  choroidal structures, the premium Cobra-S 800 delivers the speed, clarity, and depth you need.

Cobra-S near infrared spectrometers can be used for ultra high speed OCT imaging in the 650-950 nm range in research, industrial and OEM solutions. Let our expert team put together a configuration that is right for your application. Contact oct@wasatch.grafxtampa.com and let us help you to improve your image.
