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 but also the unique photometric Auto Exposure where the flash and observation light intensity is determined automatically during every examination, 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, 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 Myd Retinal Camera as far back as 1976 The CR-2 AF was built on that legacy, it is equipped with superb Canon optics and Canon’s own EOS digital camera technology, with its renowned image processing capabilities, has been adapted exclusively for Canon retinal cameras to offer optimal retinal imaging, for the highest image quality.
In addition the unique Canon Opacity Suppression feature largely suppresses the effects of cataracts and other ocular opacities.
Ease of use
The compact design of the CR-2 AF results in a short reaching distance and allows the operator to easily keep the patient’s eye open with one hand and permits an excellent view of the patient’s eye. The stage part has a specially shaped surface to act as grip; it provides easy handling for quick and efficient image capturing.
CR-2 AF provides Non Mydriatic images at a 45 degrees angle (67.5 degrees when using center of eye ball as reference).
Angle of incidence vs central angle of view
Centralized controls and multifunctional joystick
Operation panel with Centralized controls and multifunctional joystick for intuitive operation. Switches are illuminated for easy operation in darkened rooms.
The multifunctional joystick combines many functions:
It is used to control the up and down movement of optical head, which is powered for effortless operation.
Besides the shutter release button there is an alignment button to switch between view of anterior eye and 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 reduces patients’ discomfort greatly, It improves workflow since images of both eyes can be taken without hindered by pupil restriction. Ideal for photophobic patients.
Fixation Lamp shifting presets
The CR-2 AF offers the possibility to preset 4 fixation lamps patterns for the internal fixation. Each pattern has a maximum of 9 positions. Suitable to be used with various screening protocols.
The CR-2 AF was designed to be transported to a another location very easily. The camera only weighs 15 kg and has special grips for easy carrying. The RX Capture software can easily be installed on a laptop and images can be easily uploaded afterwards to a server. It makes the device very suitable for mobile screening. The entire configuration can be easily transported in dedicated transport case.
In addition the CR-2 AF is equipped with a 2X button that provides a 2x digital magnification or depending on a setting, a 30 degrees image.
Utilizing 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 the color image. It is based on the Canon EOS retina technology and proprietary image processing - using the original RAW image of the digital camera.
The image quality is fully comparable with images obtained with 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
Using the IR Photography mode it is possible to photograph the condition of the Meibomian glands, 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.
The CR-2 AF is suitable for stereo photography as well, by taking two retinal images sequentially to form a stereo pair.
The capture sequence is simple with easy stereo guides that are shown on the observation monitor. Or create a stereo set manually and create a pair in the RX software.
Stereo guide marks
A standard commercial optical stereo viewer can be used for reviewing. The individual images of the stereo pair can be aligned easily in the RX software to obtain maximum stereo effect.
