Low Flash Intensity
Non-Mydriatic Retinal Imaging,
Fast and Efficient Examinations
The 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.
CR-1 Mark II stands for efficiency and accuracy
in retinal diagnostic exams, ergonomic design
and patient-friendly functionality.
Key Features
In 1976, Canon reinvented retinal examination by developing
the world’s first non-mydriatic camera. To this day, Canon continues
Anterior eye and stereo photography are available
to set industry standards with high-quality diagnostic imaging.
Equipped with an exceptionally low flash intensity,
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.
Canon’s CR-1 Mark II non-mydriatic digital retinal camera
provides more efficient workflow, ease of use, and patient comfort.
CR-1 Mark II: Benefits of low flash intensity
For patients having non-mydriatic retinal exams, the bright flash
can be unpleasant . CR-1 Mark II focuses on reducing patient
stress to provide comfortable retinal exams by significantly
reducing the flash intensity. Because 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.
■ Selectable flash mode

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
Ergonomic controls
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.
Control options with joystick
45-degree angle of view
2x digital magnification
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” 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.
Easy alignment and focusing
Safe, secure patient positioning
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.
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.
Note: The above results were based on partnering with
the EOS 50D digital camera.
■ Quick image acquisition
Control software
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.
Viewer functions with simple saving capability
Network Capabilities
Effortless and convenient handling, printing, saving, and transmitting of all
image data to remote locations via the control software are made possible
with the CR-1 Mark II’s network capabilities. The DICOM-compliant network
interface allows CR-1 Mark II easy integration with existing medical imaging
systems and connection to PACS and HIS network configurations. The
control software and network capabilities work together for streamlining
overall diagnostic workflow.
