Haag Streit BQ 900 Slit Lamp

The BQ 900 is equipped by default with a Galilean Microscope providing a magnification range from 6.3 × up to 40 × selectable in 5 fixed steps. The high light transmission and the optical excellence ensure a superb clinical view. The large diameter of the exit pupils allows fatigue-free examination even on long working days. By reducing the angle of stereoscopic observation, the stereo variator facilitates the examination of the fundus, peripheral parts of the retina and the vitreous, even under unfavourable conditions such as high myopia and small pupils. The reduction of the angle enlarges the stereoscopic field of view, maintaining depth information in the stereoscopic observation.
