BQ 900 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.

Microscope

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.

The original Goldmann tonometer

Because it is fast and reproducible, Goldmann applanation tonometry has been the gold standard of tonometry for many decades. It is based on the Goldmann principle – tried and tested during more than 50 years of usage with millions of patients.

Imaging Modules

Intuitive Imaging - Best Results

The Imaging Modules IM 900 and IM 600 are fully integrated compact imaging solutions for the BQ 900 slit lamp. These cameras, manufactured by Haag-Streit, have excellent sensitivity, a wide dynamic range and unique ergonomics that provide full control over the imaging process without destracting from the clinical examination. The included Eye­Suite software package contains a comprehensive imaging program and permits integration of the BQ 900 into your practice network.

Wide range of applications

Fundus Module 300

 Fast and easy fundus documentation on the slit lamp

This innovative accessory allows integration of non-mydriatic retina imaging as part of the regular slit lamp examination. This can improve practice workflow and save both clinical and patient time.

Inclined Eyepiece Adaptor

Ergonomic and fatigue-free working

With the inclined eyepiece adaptor, the view into the micro­scope is inclined at 20 degrees to the horizontal. This enables the examiner the use of the slit lamp in a more comfortable, fatigue-free position. 

  Stereo Variator

Enhanced view on fundus

Unique to the BQ 900, the stereo variator reduces the angle of stereoscopic observation from 13° to 4.5°. This facilitates the stereoscopic 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 under the described conditions, maintaining depth information in the stereoscopic observation.

 Yellow Filter

Fluorescence enhancement

This yellow barrier filter provides additional contrast to fluo­rescein images. It can be mounted permanently on the slit lamp and easily enganged if required.

Beam Splitter

Connection 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 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

Analog co-observing

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 sittting posi­tion and a long version for co-observing in upright position
