Haag-Streit BM900 LED Slit Lamp

Reliable optics – enduring performance

The BM 900 has been the standard in modern slit lamp microscopy for more than 55 years – and still is! Over 100,000 professionals all over the world who own a BM 900 agree that it was the best investment they ever made for their practice.


Equipped with a Kepler microscope, the BM 900 provides two standard magnifications: 10x and 16x. With a set of optional oculars it can be extended to 25x and 40x magnification. Like any other Haag-Streit slit lamp, the BM 900 features the best optical components to show all structures of the human eye in every detail.

Illumination system

Over the last years, LED illumination has become standard in modern slit lamp microscopy. It delivers our sharpest and most homogeneous slit ever. A tilting frame allows good posterior segment observation, while the defocusing option enhances observation with indirect illumination. All filter and slit controls are conveniently situated for ease of use and, as with the cross slide mechanism, have a silky smooth, effortless movement. The slit mechanism is a masterpiece of engineering in itself, affording faultless precision in both shape and movement.


Cross slide

This cross slide mechanism, incorporated into all Haag-Streit slit lamps, introduced one-handed operation of the slit lamp many decades ago. Perfection in design, materials and construction allow these movements to be made smoothly and effortlessly without any wrist or finger strain and to continue doing so for the very long lifetime of this classic slit lamp.
