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
Like all Haag-Streit slit lamps, the BQ 900® features the unique cross slide mechanism allowing effortless positioning of the slit lamp. With the patented joystick, movements in vertical and horizontal directions are possible. |

Illumination
The well established tungsten (optional halogen) slit illumination paired with precision mechanics and high quality optics establish an excellent slit image with highest brightness from 8 mm length and width to a hairline. The possibility to rotate the slit 90° around the optical axis on either side, tilting it up to 20° and decentring it, lets you find the right adjustment for all examination situations. |
