Cobra-S 800 Series - Image 2

Cobra-S 800 Series

High resolution, high speed & proven imaging performance

Launched in 2017, the Cobra-S is our original and most popular high-speed spectrometer for near infrared OCT laboratory research. It is used in research applications in ophthalmology and materials processing as well as more specialized techniques like polarization-sensitive OCT (PS-OCT) and optical coherence elastography (OCE). It is cited widely in literature, and we continuously marvel how this enabling technology is helping academics push the boundaries of OCT research.

Cobra-S 800 part numbers are of the format CS800-[CWL]/[BW]-[kHz]-[camera][pixels]-[interface], where the e2v OctoPlus camera is represented by “OC”, 2K denotes 2048 pixels, and the interface is either camera link (up to 250 kHz, denoted by “-CL”) or USB 3.0 (up to 130 kHz, , denoted by “-U3”). Imaging depth stated is the theoretical value, calculated in air.

    USB-3.0: 20kHz, 80kHz, 130kHz

  • •

    Camera Link: 250kHz

Like our flagship Cobra-S 800, the Cobra VIS 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.
