The SL-520 is 5 Step Slit Lamp and it’s features a parallel Galilean optical system with stereoscopic binocular imaging and a five-step magnification range (6x, 10x, 16x, 25x, 40x). It supports upgrades to teaching and digital configurations and uses a long-life warm LED illumination system with PWM-stabilized brightness and continuous intensity control.

For clinics that prefer a simpler setup, the SL-320 3-Step Slit Lamp offers the same optical platform and LED illumination system with a streamlined three-step magnification design (10x, 16x, 25x), making it suitable for routine anterior segment examination.

Base with stepless dimming

The base supports stepless dimming with PWM-stabilized output, so brightness adjusts cleanly without flicker. This gives you precise control of illumination at any magnification level—whether you're observing the cornea, anterior chamber, or deeper structures.
