*Refurbished* Zeiss Cirrus HD-OCT 4000 System
 
Zeiss Cirrus HD-OCT 4000 System delivers superior image data. The new Enhanced Raster Scan leverages this power to produce images with outstanding detail while maintaining patient throughput. The proprietary Selective Pixel Profiling technology enhances anatomical features while reducing image noise.
 
Zeiss Cirrus HD-OCT 4000 System enables repeatable visualization of clinically relevant anatomy with exact correlation between the OCT scan and the fundus image. Comprehensive navigational tools ensure efficient and simple operation.
 
Features:
Small footprint and integrated design are ideal for crowded or busy practice
90 degree orientation facilitates observation of patient throughout exam
Advanced optics aid in the examination of patients with cataracts
Dilation is not required even for pupils as small as 2.5 mm
Mouse Driven Alignment™ delivers superior image capture and analysis in just a few clicks, resulting in reduced chair time for the patient
Auto Patient Recall assures patient position and instrument setting are repeated from previous visit
