Cirrus 4000 HD OCT! Complete system and the latest OCT offered from Zeiss. This HD interface is very efficient, easy to use and will network with many other Ziess products. The Cirrus 4000 is one of the fastest OCTs on the market.

Cirrus HD optical coherence tomography instrument uses spectral domain technology to capture exquisite volumetric (3D) & high definition line scans of the retina for precise detail of retinal tissue and pathology. The Cirrus has advanced hardware and software that facilitate automated alignment and high patient through-put. An elegant user interface and fast electronics mean chair time is shortened. The Cirrus HD-OCT realizes the superior capabilities of ZEISS optics and provides exquisite high definition images and analyses for enhanced clinical confidence. It provides beautiful high definition OCT scans and LSO fundus images providing visualization of retinal structure.
