Optical Design
High-performance Greenough Microscope

The convergent binocular tubes ensure easy fusion and stress-free observation.

Extended Slit Length

The diameter of the slit length is extended to 14mm from 10mm. This allows 30GL to illuminate a wider area of the anterior segment.

Magnification Changer
30GL is fully equipped with a 2-step magnification changer that offers 10x and 16x powers; magnification can be easily changed with the magnification change lever. With the use of 16x eyepieces, total magnification can be increased up to 25x.


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.

Various Options
Patient’s hand rests, Applanation tonometer, and optional eyepieces for 30GL are available according to users’ requirements and application.


Design

High-grade Slit Lamp without a cable  

Innovative Design: No cables are exposed. Even the power supply cable is concealed.
Conventional power cable from the chinrest to the light housing has been eliminated – now neatly concealed inside the slit lamp body.
30GL looks neat and compact with no exposed cables, giving a sleek look with an innovative design.  
New product color

LED

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, 30GL has been designed and engineered from scratch to accommodate the new superior LED lamp.
LED optimized 30GL provides brighter and sharper light.

Use of Uniform LED Illumination

The LED slit lamp with a color temperature of 3500 K provides brighter and sharper light than halogen.
A 1-element high-luminance LED is used for 30GL 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.
