Professional imaging solution

Universal adapter mount

Benefit from the best camera systems on the market. The Haag-Streit BX 900 slit lamp can be equipped with various professional camera systems thanks to its universal adapter, which is elegantly located above the slit lamp microscope.

Enhancing light capture

Xenon flash

The main illumination is supported by a powerful xenon flash during the capturing process. The flash tube is located coaxial with the LED illumination and exactly reproduces the illumination pattern of the slit to provide images of impressive quality. The brightness of the flash is individually adjustable for slit and background illumination.

Let there be light

Mirror housing

The centrepiece of the BX 900 slit lamp is the mirror housing with its built-in diaphragm and 5 step aperture control. Light is a crucial factor in ophthalmic photography—the mirror housing redirects 100% of the available light to the camera sensor during the capturing process to ensure maximum light availability in every situation.

Swap tungsten for LED

Convert your slit lamp today

Enhance your older Haag-Streit slit lamps by converting them to use a 14mm LED illumination system. Many eye clinics are still using tungsten bulbs in slit lamps, which can lead to equipment down-time when the bulb needs to be replaced. Frequent bulb changes in busy clinics can be costly. LED illumination reduces energy consumption by 60%, lasts up to 150 times longer than a tungsten bulb and has the added benefit of providing improved illumination of the anterior segment for clinical diagnosis.

An LED enhancement is quick and simple to perform, with little downtime. Our Service Engineers will visit you and install the conversion kit in just a few hours. For further information, click here to download the leaflet, or alternatively call the HS-UK Service Division on 01279 456314 or email
