CR-2 AF

The CR-2 AF is a Non-Mydriatic Camera with extensive auto functions. Taking images with a Canon retinal camera has never been easier!

The camera offers fast and accurate Auto-Focus, Auto Switching from anterior to retinal observation and Auto Shot. This device also features the unique Photometric Auto-Exposure whereby the flash and observation light intensity is determined automatically during every examination. This is based on real-time measurement of retinal reflectance for perfect images in a single capture, regardless of pupil size or ethnicity.

For patients with ocular opacities, involuntary eye movements, a lack of co-operation and small pupils, the CR-2 AF also provides full manual control.

See the smallest details, don’t miss pathology

Canon was the very first company to introduce a Non-Mydriatic Retinal Camera as far back as 1976. Built on this legacy, the CR-2 AF is equipped with superb Canon optics and Canon’s own EOS digital camera technology. The technology includes Canon's renowned image processing capabilities, which has been adapted exclusively for Canon retinal cameras in order to offer optimal retinal imaging for the highest image quality.

In addition, Canon's unique Opacity Suppression largely suppresses the effects of cataracts and other ocular opacities.

Ease of use

The CR-2 AF’s compact design results in a short reaching distance and allows the operator to easily keep the patient’s eye open with one hand while offering an excellent view of their eye. The stage part consists of a specially shaped surface to act as grip; it provides easy handling for quick and efficient image capturing.

45 degrees

CR-2 AF provides Non-Mydriatic images at a 45 degrees angle (67.5 degrees when using the center of an eye ball as reference).

Centralized controls and multifunctional joystick

The operation panel comes with centralized controls and a multifunctional joystick for intuitive operation. The switches are illuminated for easy operation in darker rooms.

The multifunctional joystick combines many functions:

Controls the up and down movement of the optical head, which is powered for effortless operation.
Apart from the shutter release button, includes an alignment button to switch between the view of the anterior eye and the retina, and a focus ring that can be used for manual focus control.

Low flash photography

In addition to the photometric Auto Exposure, the CR-2 AF offers low flash photography. This greatly reduces the patients’ discomfort. Workflow is also improved as images of both eyes can be captured without being restricted by the pupils’ size. This is ideal for photophobic patients.

Fixation Lamp shifting presets

The CR-2 AF offers the possibility to pre-set four fixation lamps patterns for internal fixation. Each pattern has a maximum of nine positions. This is an excellent feature when various screening protocols are used.

Portability

The CR-2 AF was designed to be easily transported to alternate locations. The camera’s weight of 15 kg with its special grips makes it effortless to carry in its dedicated transport case. The RX Capture software can be conveniently installed on a laptop and images can readily be uploaded afterwards to a server.

2X Magnification

The CR-2 AF is equipped with a 2X button that provides a 2X digital magnification, such as a 30 degrees image, depending on the setting.

Wide Field Imaging

With the optional Mosaic software, up to 20 images can be combined into a high-resolution wide field image including the peripheral retina (up to 85 degrees).

The automatic fixation light guidance of the retinal camera can be of assistance in capturing the images.

Digital Redfree and cobalt image

Without having the requirement to take an additional image, the RX software can create a digital red-free or cobalt image from a colour image. This is based on Canon’s EOS retina technology and its proprietary image processing that uses the digital camera’s original RAW image .

The image quality is fully comparable with those obtained via optical filters.

Anterior Segment Photography

The CR-2 AF offers quick and easy anterior segment photography to document the cornea, pupil, eyelid and sclera.

Anterior IR photography

The IR Photography mode offers the possibility of photographing the Meibomian glands’ condition, an important factor related to dry-eye conditions. Failure of these glands will affect the quality and stability of the tear film, which in turn will produce classic dry-eye symptoms.

Stereo Photography

Stereo guide marks

The CR-2 AF is suitable for stereo photography by sequentially taking two retinal images to form a stereo pair.

The capture sequence is simple to use with its stereo guides shown on the observation monitor. Alternatively, users can manually create a stereo set as well as a pair in the RX software.

Stereo viewing

Stereo Pair

A standard commercial optical stereo viewer can be used for reviewing. The stereo pair’s individual images can easily be aligned in the RX software for maximum stereo effect.
