Product Description

The Burton SL-3MH Slit Lamp uses a Haag-Streit style Tower Illumination system and features Galilean optics to provide easy fusion for the care giver. The three magnifications (10x, 16x, 25x) are easily switched with the ergonomically designed selection drum. Over-sized eyepieces for an excellent field of view and the rheostat next to the omni joystick make this a very user-friendly option for any practice.
