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.
