LED Illumination
The new LED powered slit lamps delivers our sharpest, brightest and most homogeneous slit ever. The light spectrum is specially designed for Haag-Streit to fulfil the high quality standard and matches the well established tungsten light. This ensures best details in diagnosis from the cornea to the retina. The LED illumination LI 900® is available for the Haag-Streit Slit Lamps BQ 900®, BM 900® and BP 900®. |

Cross Slide Mechanism
This cross slide mechanism, incorporated into all Haag-Streit slit lamps, has both its vertical and horizontal movements controlled by our patented joystick. Perfection in design, materials and construction allow these movements to be made smoothly and effortlessly without any wrist or finger strain – and to continue so for the very long lifetime of this classic slit lamp. |

Illumination System
The heart of the Haag-Streit slit lamp (also on the BQ 900® and BP 900® models), the illumination system has the brightest illumination available in a slit lamp providing a tilting, rotating slit of up to 8 mm in length and width. Tilting is extremely important to good posterior segment observation. 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, one of those "differences inside", is a masterpiece of engineering in itself, affording faultless precision in both shape and movement. |
