    The Haag-Streit BQ 900 LED Slit Lamp adds LED technology to this proven slit lamp. Due to its excellent optics, versatility and ease of operation, it has become the standard for those requiring advanced slit lamp microscopy. A universal, modular system, the BQ offers simultaneous video and still photography through either professional or consumer level cameras. It offers a range of optional accessories include a teaching scope, inclined eyepiece and for the retinal specialist, the unique stereo variator. As with all Haag–Streit slit lamps, a Goldmann tonometer: the gold standard in IOP measurement may be added onto the system.

    Beam Splitter

    The "key" to a wide range of accessories, the beam splitter diverts a portion of the light to secondary attachments such as the second observer tube, video, 35mm or digital cameras. There are two ports which allow for simultaneous video and still photography or alternatively, use of the second observer tube with either video or still cameras. The beam splitter can stay attached to the slit lamp. Then, when needed, can be easily utilized with a lever allowing for the full 100% of light to be sent back to the user's eyepieces.

    Inclined Eyepiece Adaptor

    This simple but effective device allows the eyepieces to be inclined upwards by 20 degrees from their traditional horizontal position, thereby reducing neck strain and allowing a more natural viewing position to the user.


    The magnification can be continuously changed from 6 up to 40x. Reference points are set at magnifications 10, 16 and 25x.

    Second Observer Tube

    A second observer tube can be used for teaching and training purposes.

    Stereo Variator

    Uniquely with the BQ 900, an optional stereo variator reduces the 13 degree angle to 4.5 degrees. This enlarged binocular field of view is possible even with myopia or through small pupils. This also aids the observation, without additional lenses, of the peripheral fundus and vitreous.

    The convergent stereo view offers a very large binocular field of view with high resolution and depth of focus. Eyepieces adjustable to all papillary distances allow for a fatigue free and relaxed examination, even during long examinations.
