Key features
|
True 45-degree
image The CR-1 features a
redesigned optical system that achieves
h i g h - r e s o l u t i o n diagnostic
images at a 45° angle of view.
|
 |
 |
2x digital magnification
“2x” mode provides a closer, more
magnified view of the retina. It works
by automatically cropping out the
peripheral edges of the image so that
the region of interest is larger in the
frame. Closeups are extremely clear and
detailed thanks to the high pixel count
of the attached digital camera. |
Motorized chin rest
The motorized chin rest can be moved up
and down to accommodate the patient's
height using a pair of buttons located
on the operation panel. |
 |
 |
Internal
fixation target adjustment
The finely calibrated internal eye
fixation target of the CR-1 provides the
patient with a fixed, consistent point
of focus throughout the image capture
procedure, making it quick and easy to
achieve a clear and stable image. The
fixation target LED can be freely
adjusted via the operation panel to
position the eye exactly as desired. One
push of a button returns the target to
its default position.
A swivel type external
eye
fixation target is available as
an option and sold separately. |
Shorter working distance
A shorter working distance allows closer
interaction with the patient, plus easy
access
to the patient’s eyes. |
 |
 |
Anterior eye and stereo photography
are available |
Illuminated operation panel
The illuminated operation panel
enables easy one-handed
operation in darkened rooms. |
 |
Designed and engineered for outstanding image
quality and ease-of-use, plus greater patient
comfort

Ever since developing the
world’s first non-mydriatic retinal
camera in 1976, Canon has been a pioneer
in the field of retinal imaging. Canon’s
latest advancement, the non-mydriatic
digital CR-1, combines state-of-the-art
optics and retinal imaging technology
with the renowned EOS digital SLR system
to provide industry-leading image
quality and efficiency. All this, in an
all-new
ergonomic design that’s more comfortable
for the patient and easier to use than
ever before. |
|
|
High-quality,
high-resolution images
The CR-1 features a redesigned
optical system that achieves extremely detailed,
high-resolution diagnostic images of the retina
for accurate detection and monitoring of ocular
conditions including diabetic retinopathy,
glaucoma, and macular degeneration. The high
pixel count of the attached EOS digital SLR
camera delivers detailed image quality even when
magnified. Once captured, images are transferred
to a connected PC for review. |
|
Comfortable,
ergonomic
design
The all-new design
of the CR-1 integrates
advanced specifications into an
ergonomic unit that facilitates
operation by motorizing procedures
usually performed by hand. The intuitive
controls, viewing monitor, and the
streamlined form have all been designed
for improved ease of use and comfort.
It’s also patient-friendly. Because
retinal images are easy to obtain, exams
can be completed in less time. |
Easy alignment and
focusing
Image capture is fast and easy thanks to a
simple two-step procedure.
First, you align the two halves of a split pupil
image. Then you switch to the retinal display,
and adjust the split lines and working distance
dots to achieve the correct focus and distance
to the retina for clear, sharp images every
time.

Step 1:
Split pupil alignment |
Step
2: Retinal image adjustment
|
Streamlined system and
workflow
The efficiency of the CR-1 goes beyond image
capture. The network
capability and control software of the CR-1 work
to streamline the entire diagnostic workflow,
allowing you to conveniently review, analyze,
print, store and transmit images to remote
viewing locations. The DICOMcompliant network
interface enables easy integration with existing
image management systems and allows connection
to a variety of network configurations such as
LAN, WAN and PACS. The bundled Retinal Imaging
Control Software for the CR-1 puts tools for
comprehensive study management and image capture
control at your fingertips, in an intuitive
graphical interface that’s simple and
straightforward to use. The PCbased software
provides quick, easy input and access to all
information and images required to assist in
your diagnosis.
