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.

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.

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.

Inclined eyepiece adaptor
With the inclined eyepiece adaptor, the view into the microscope is changed to a more ergonomic and fatigue-free working position.
SOPHISTICATED MICROSCOPY
Inclined eyepiece adaptor
Adjusting the viewing angle at 20 degrees on the slit lamp allows the examiner to adopt a more natural neck position.

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.
SOPHISTICATED MICROSCOPY
Yellow filter
After fluorescein instillation and cobalt blue light illumination, visualization with a yellow barrier filter provides higher contrast images.

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.
