Carl Zeiss Cirrus 400
AMERICA North (USA-Canada-Mexico)
The ZEISS Cirrus HD-OCT 400 (Cirrus HD-OCT or Cirrus) enable examination of the posterior and anterior of the eye at an extremely fine spatial scale,
without surgical biopsy or even any contact with the eye.
The Cirrus HD-OCT builds on and refines the retinal imaging technology first introduced
with the ZEISS Stratus OCT™.
HD-OCT stands for "high-definition optical coherence tomography."
Employing the advanced imaging technology of spectral domain optical coherence tomography,
Cirrus HD-OCT acquires OCT data about 70 times faster (27,000 vs. 400 A-scans per second)
and with better resolution (5 μm vs. ~10 μm axial resolution in tissue), compared to first-generation OCT technology.
Cirrus acquires whole cubes of OCT image data,
composed of hundreds of line scans, in about the same time as Stratus acquires a six-line scan.
