ZEISS Cirrus 4000 HD-OCT

The ZEISS Cirrus HD-OCT 4000 allows 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.

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.
You can view these data cubes in three planes,
or through three dimensions, giving you access to
an extensive amount of retinal image data in one scan.
