Cobra 1600 OCT Spectrometer

Superior depth & contrast for highly scattering samples


  • Optical coherence microscopy
  • Intravascular OCT
  • Non-destructive analysis

Cobra 1600 Setup Guide

Visualization of deep-tissue structures can be limited in penetration depth and contrast, particularly for samples with high scattering power & low water content, such as lipid-rich tissue, dental structures, and even paints and rubber.

As the first commercially available off-the-shelf 1600 nm OCT spectrometer, the Cobra 1600 gives you access to an optical window with enhanced depth penetration and high contrast with high axial resolution, compatible with readily available fiberoptic components. Our proprietary high throughput design offers the sensitivity & speed needed for 3D deep-tissue imaging to study hippocampal formation and characterize atherosclerotic plaques, or for non-destructive testing.

Cobra 1600 OCT spectrometers can be used for en face and 3D imaging in research, industrial and OEM solutions. Need a different center wavelength or bandwidth than the models below? Contact us to discuss your application and needs.
