Model: SL-320
The SL-320 is 3 Step Slit Lamp, and uses a parallel Galilean optical system with stereoscopic binocular fusion and offers three-step magnification (10x, 16x, 25x). It supports upgrades to teaching or digital configurations and includes a long-life LED illumination system with stable PWM brightness control.
For users who need a wider magnification range, the series also includes the SL-520 5-Step Slit Lamp, which provides 6x, 10x, 16x, 25x, and 40x magnification through a revolving drum while keeping the same optical platform and illumination system.

SL-320 uses a warm LED light source rated for 20,000 hours. It keeps the illumination stable and comfortable for both doctor and patient, and reduces the need for frequent lamp replacement.

The base supports stepless dimming through PWM illumination, letting you adjust brightness precisely without jumps. This makes it easier to fine-tune lighting for different corneal and fundus observations.
