The Haag-Streit BX 900 slit lamp combines the latest imaging technology with the proven versatility, optical brilliance and mechanical quality of the Haag-Streit tradition.
Please tell me more about BX 900
The photographer's slit lamp
The BX 900 is THE leading slit lamp imaging device. It comes equipped with LED slit illumination which offers an extremely sharp and homogenous slit, providing clinicians with diagnostic confidence. An integrated flash and camera are mounted above the microscope to allow ease of access to the patient. This is especially useful when photographing in conjunction with hand-held diagnostic lenses.
The high power flash illumination is delivered via a xenon tube that lies coaxially to the LED illumination and thus exactly reproduces the slit illumination pattern to provide images of stunning quality. The brightness of the flash is individually adjustable for slit and background illumination.
The heart of the BX 900 is the mirror housing with its built-in diaphragms. When capturing an image, all light is directed via a mirror to the camera. This allows the maximum utilisation of the available light: 100% for the examination and 100% for the image. The built-in diaphragm setting with five apertures is applied automatically on image capture.
Conveniently mounted close to the operator’s hand, this can easily be utilised whilst continuously maintaining focus with the slit lamp joystick. As it is symmetric on the cross slide, it allows right- and left-handed operation.
Improved efficiency - optimal examination
As supplier of complete solutions, Haag-Streit offers a wide range of accessories of great benefit to the ambitious slit lamp user.
Tables and units
Haag-Streit offers a wide range of instrument tables that fit most ophthalmic products, from slit lamps to bowl perimeters. The HSM 901 ans HSM 600 series tables fit complex diagnostic systems, featuring cable guides and other handy design detail.
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.
Eyepiece with crosshair reticule
The use of this eyepiece ensures perfect focus of the microscope image onto the camera by compensating for user accommodation.
This accessory diffuses the light to provide an improved general overview of the eye when the slit lamp is used at low magnification. Especially for imaging this accessory is indispensable.
Short illumination mirror
When working with small illumination angles (e.g. for fundus examination) the standard mirror obscures one of the optical pathes partially or completely. The short mirror allows unobstructed view but requires that the illumination is tilted by 10° in order to have the complete light patch on the mirror.
While all new Haag-Streit slit lamps are sold with LED illumination there are thousands of tungsten slit lamps in the market. For these slit lamps Haag-Streit recommends the upgrade to LED. If for some reasons an upgrade is not considered users should only use the original Haag-Streit Tungsten lamp bulb to get the best performance from their Haag-Streit slit lamp.
The headrest has been designed according to anatomical criteria and includes an adjustable chinrest. The unique fixation device permits uninterrupted observation and simultaneous guidance of the patient's eye which helps to make examination more comfortable for operator and patient. The headrest is available with and without fixation device.
