Haag-Streit BQ900 LED Slit Lamp

Sophisticated microscopy – outstanding performance

Thanks to its excellent optics, versatility and ease of operation, the BQ 900 has become the standard for those requiring the most demanding slit lamp microscopy. A wide range of optional accessories provide convenient conditions for every examination. 

Product Overview

Optical excellence

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.

Stereo variator

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.

Inclined eyepiece adaptor

With the inclined eyepiece adaptor, the view into the microscope is inclined at 20 degrees to the horizontal. Consequently, the examiner is able to maintain his head in a fatigue-free position.

Zoom objective

With the zoom objective, the magnification can be continuously changed from 6 up to 40 x. Reference points are set at magnifications 10 x, 16 x and 25 x to allow easy orientation. The zoom objective offers excellent diagnostic capabilities – especially when used in conjunction with video function. Any existing BQ 900 can be modified from a standard model to a BQ 900 – Zoom.

Yellow filter

This yellow barrier filter provides additional contrast to fluorescein images. It can be mounted permanently on the slit lamp and easily inserted or removed as required.

Beam splitter

The beam splitter diverts a portion of the light to secondary attachments such as second observer tubes and video- or digital cameras. Beam splitters are available in different versions. The beam splitter for cameras diverts 70% of the light to the secondary attachment, the one for co-observation under equal conditions diverts only 50% of the light. Video or digital cameras can be connected to the beam splitter with a range of C-mount adaptors, which offer different focal lengths for variable sensor sizes.

Second observer tubes

Haag-Streit’s second observer tubes are designed to permit professional colleagues, students or technicians to participate in the examination. There are two versions of second observer tubes available: a short version for co-observing in sitting position and a long version for co-observing in upright position.
