Introduction

Features

The Canon Digital Retinal Camera CR-2 takes digital photographic retinal images of patient's eyes

across an angle of view of 45 degrees, in a naturally dilated state without using mydriatics. The CR-2

has the following features.

Reduced flash intensity

The CR-2 can take images at ISO 1600 at the standard flash intensity, and ISO 6400 in low flash

intensity mode. This reduces patient discomfort caused by light glare.

Compact, user-friendly design

The CR-2 is designed to be even smaller, more lightweight and compact. This makes it easier to

assist patients and provides significantly improved ease-of-operation.

An integrated operation lever has been adopted for vertical movement of the main unit, switching

between anterior eye and retina, and focus operations, which significantly improves alignment

operability.

Special digital camera

The CR-2 is equipped with a special digital camera using EOS digital technology. This enables the

CR-2 to fully maximize Canon technology for shooting high-quality, high-resolution diagnostic images.

Small pupil photography function

The CR-2 take retinal images through pupils of the normal diameters from 4.0 mm. When using the

small pupil photography function, it can take through pupils of the diameters from 3.3 mm.

System optimized for digital photography

With the Retinal imaging control software, the photographed images can be browsed, processed,

stored, output to the DICOM storage server, exported in DICOM or JPEG format and output to a

printer.
