Canon CR-1

The Canon CR-1 Mark II Digital Retinal Camera epitomizes state-of-the-art non-mydriatic imaging technology with dramatically reduced brightness, improved overall comfort, and significantly shorter exams. For patients having non-mydriatic retinal exams, the bright flash can be unpleasant. The CR-1 Mark II focuses on reducing patient stress to provide comfortable retinal exams by significantly reducing the flash intensity.

CR-1 Digital Non-Mydriatic Retinal CameraBecause retinal exams play an important role in screening for major illnesses, the ease of examining provided by the CR-1 Mark II supports overall healthcare for people.Features

• Benefits of Low Flash Intensity

Efficiency of non-mydriatic retinal exams heavily depends on a patient’s darkness adaptation period. The low flash intensity of CR-1 Mark II minimizes miosis, thus shortening the time required for taking multiple pictures such as binocular and stereo images. The reduced brightness induces more patient compliance, leading to speedy and accurate exams for high throughput screening.

• High-Quality Retinal Imaging

Canon’s expertise in the field of imaging technology supports CR-1 Mark II’s exceptional digital retinal imaging capabilities. High-resolution diagnostic images of the retina are extremely detailed and clear, a necessity to effectively detect and monitor ocular conditions such as diabetic retinopathy, glaucoma, and macular degeneration.

• 45-Degree Angle of View

The CR-1 Mark II features an optical system that achieves high-resolution diagnostic images at a 45° angle of view suitable for health check-ups and screening.

• 2X Digital Magnification

“2X” mode provides a magnified view of the retina for viewing the details of the region of interest. Sharp images are made possible by the attached EOS digital SLR camera’s high pixel count.

• Ergonomic Controls

CR-1 Mark II has an ergonomic design to simplify operation for the user. A one-hand joystick repositions the camera to the exact view desired. The illuminated operation panel, featuring easy-to-understand control options, has been designed for quick adjustment and selection of the necessary settings. A short reaching distance between the patient and operator allows closer personal interaction and easy access to the patient’s eyes.

• Safe, Secure Patient Positioning

An adjustable motorized chin rest, forehead guard, and front protection cover perfectly situate the patient securely in position for the exam while ensuring their safety during operation. An optional external fixation target is also available.

• Easy Alignment and Focusing

Two simple steps are all it takes to capture a clear image. Step 1 is the aligning of two halves of a split pupil image, followed in Step 2 by the adjustment of split lines and working distance dots in the retinal display. This ensures that the correct focus and working distance are achieved for the sharpest images possible.

• Retinal Imaging Control Software

The bundled Retinal Imaging Control Software for the CR-1 Mark II puts tools for comprehensive study management, image capture controls, and easy viewing at your fingertips. The intuitive graphical interface is simple and straightforward to use. The PC-based software provides quick input and access to all information and images required to assist in your diagnosis, and data can be easily saved to various external media.

• Printers and Projectors

If your imaging requirements include color or black-and-white prints in a variety of sizes, Canon printers offer the terrific blend of print quality, ease-of-use, speed, and cost-effective operation. For teaching facilities and conference rooms, Canon’s high quality projectors provide LCOS (liquid crystal on silicon) technology, which is engineered to provide exceptional color, intricate details, and easy-to-read type.
