.
4ZL: High-performance with a 5-step magnification changer
2ZL: Excellent performance with a 3-step magnification changer
Innovative Design: No cables are exposed. Even the power supply cable is concealed.
Even cables for connecting an imaging system can be concealed.

New LED Optimized Slit Lamp
. One of the best advantages of LED illumination is that affected anatomy and structures
of the eye can now be more clearly and visibly seen because the peak wavelength of
LED light appears in the region which is more sensitive to the human eye.
. We haven’t simply replaced the halogen light source with an LED type, 4ZL / 2ZL have
been designed and engineered from scratch to accommodate the new superior LED lamp.
. LED optimized 4ZL / 2ZL provide brighter and sharper light.

Use of Uniform LED Illumination
. The LED slit lamps with a color temperature of 3500 K provide brighter and sharper light
than halogen.
. A 1-element high-luminance LED is used for 4ZL / 2ZL providing a uniform and even
light compared to multiple element LED's.
Reduction of the Characteristic Blue Light of LED
. The projected light is soft and easy on patients’ eyes by reducing the peak of the
characteristic blue band spectrum of LED.
Bright and Sharp LED light source
Optical Design
Converging Binoculars
. Binocular tubes with a 6-degree convergence provide easy binocular fusion, ensuring
stress-free observation.
Usability and Ergonomics Tailored for You
Improvement of Usability
. The size, placement and other features of various controls are reconsidered based on
ergonomics in order to enhance usability
Built-in Background Illumination (4ZL only)
. For use with an imaging system, the background illumination is now equipped in 4ZL as
standard.
. The color balance of an image taken through 4ZL is not lost because the same LED is
used for both main light source and background illumination.
. Intensity of the background illumination is adjustable by hand using the lower left hand
side control.
4ZL: High-performance high-grade slit lamp with a 5-step magnification changer,
a powerful all-rounder offering total application flexibility
2ZL: Functional high-grade slit lamp with a 3-step magnification changer,
an all-rounder ideally suited for routine screening applications
Reduction of Patient’s Uneasiness
. When 4ZL / 2ZL are switched on, a circular blue LED lights up around the lower part of
the slit unit, which does not disturb the examination. The blue LED light is associated
with mental calmness, reducing patient’s uneasiness.
. Because the circular blue LED indicates the power is on, the users can examine with
4ZL / 2ZL at ease.
Various Options
. Patient's hand rests and various other options for 4ZL/2ZL are available according to
users' requirements and application.
