Carl Zeiss Cirrus HD OCT 4000

CARL ZEISS CIRRUS HD OCT 4000

Carl Zeiss Cirrus HD OCT 4000 delivers detailed diagnostic and change analysis you can rely on. The small footprint and fast capture speeds of the Cirrus 4000 improve work efficiency while helping you to deliver better care to your patients. The Cirrus 4000 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.
