ADVANTAGES & BENEFITS OF LED

LED LIGHT SOURCE
The new LED illumination source allows observation under a brighter, more homogeneous condition than the
conventional halogen bulb source. The short wavelength of the LED spectrum enables the operator to see minute
details such as flare in the anterior chamber and vitreous. Color temperature remains uniform when adjusting light
intensity insuring consistent viewing results throughout the entire eye’ s optical path.

LED FEATURES
» Brighter illumination enhances observation of the

eye structures
» LED wavelength characteristics allow for easy

visualization of subtle details such as flare and
inflammation
» Consistent color temperature throughout the entire
light intensity adjustment
» Substantial reduction in bulb replacement
» Energy efficient and cost saving

ADDITIONAL FILTERS

BLUE FREE FILTERTM SYSTEM
Topcon Blue Free Filter observation can be carried out using the exciter* filter for slit lamp and barrier* filter for slit
lamp. Tear flow details and scars can be clearly viewed with less glare or pooling.

AMBER FILTER

A warmer, more pleasant tone of the skin and eye structures can be obtained by inserting the amber filter. This
color correction filter produces a pleasant coloration that is especially useful in slit lamp imaging.

MEIBOMIAN GLAND OBSERVATION &
OTHER FEATURES

MEIBOMIAN GLAND OBSERVATION

Meibomian gland observation can be performed and documented using the optional meibomian gland observation
system*. Because of the high resolution of the DC-4, fine detail of glandular acinus and subtle changes of
meibomian glands can be seen and photographed for a better understanding of its condition.

* System of SL-D701 +DC-4 (optional) + BG-5 (optional)

RIGHT / LEFT EYE INDICATOR
When in photography mode, the SL-D701 automatically
recognizes the patient's right and left eye, simplifying the photographic
procedure.

MORE THAN JUST THE BASIC FUNCTION
Versatile lens coatings, including a preservative layer, and the use of
apochromatic optics enhance the observation and require less
maintenance.
