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 seated position, and a long version for co-observing in upright position.

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, while the other—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 adapters, which offer different focus length for variable sensor sizes.

The chin rest cup for Haag-Streit slit lamps is a removable, easy to clean, easy to disinfect and therefore safe, chin rest cup. Offering a great alternative to chin rest papers, the rest cup mold fits perfectly into the existing shape of the chinrest, and stays in a secure position.

This eyepiece provides a reticle in the optics which shows a grid with different density patterns. These patterns allow the observer to estimate the cell density of the endothelium. It is recommended for use in combination with the contrast-enhancing 2.2 x contact lens to provide enhanced viewing of the endothelium.

The standard eyepieces of these slit lamps provide magnifications of 10 x and 16 x. For higher magnification, Haag-Streit offers optional 25 x magnification eyepieces which provides an overall magnification of the microscope of 25 x and 40 x.

For all older Haag-Streit slit lamps still operating with tungsten illumination, we offer simple upgrade packages to LED illumination.

A compact shield provides the minimum protection.

Comfortable operation with contact lenses. Can be stacked to obtain different working heights.

When working with small illumination angles (e.g. for fundus examination), the standard mirror obscures one of the optical paths partially or completely. The short mirror offers an unobstructed view, but requires that the illumination is tilted by 10° in order to ensure the complete light patch on the mirror.

For BQ 900 & BP 900 slit lamps

With the BQ 900 video adapter, it is possible to add video or digital cameras to the beam splitter. We recommend the f75 adaptor for 12.7 mm / 1/2 inch sensors. Integrated in the adapter is an aperture control, which allows you to easily control the depth of field.

With the BQ 900 video adapter it is possible to add video or digital cameras to the beam splitter. We recommend the f75 adaptor for 19.5 mm / 1/3 inch sensors. Integrated in the adapter is an aperture control which allows to control the depth of field.

A bright and even background illumination is an important factor for all imaging applications on the slit lamp. All LED illumination heads are pre-configured, so that only the fiber optic need to be connected. The fixed variant has the advantage that it does not restrict the operation area between slit lamp and patient.
