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.
Since electronic documentation and patient education are on the rise, every eye care professional has the need for imaging. As the leader in slit lamp imaging, Haag-Streit is meeting this need with the introduction of two new imaging systems – the IM 600, a more basic, and the new IM 900, a very sophisticated version. With both solutions Haag-Streit sets new standards in digital slit lamp imaging.
This innovative accessory offers all users of current Haag-Streit slit lamps access to instant documentation of the retina. The impressive simplicity of the Fundus Module 300 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.
Haag-Streit offers two models of Goldmann applanation tonometers: the AT 900 a purely mechanical instrument and the AT 900 D which introduces advantages from digital technology.
[Translate to Französisch:] Tonosafe™ is a disposable measuring prism for all Goldmann applanation tonometers as well as the Perkins tonometer. Tonosafe™ disposable prisms are a convenient, effective method of reducing the risk of cross infection between patients.
The reusable Goldmann measuring prisms are distinguished by their optical and mechanical performance which allows for fast and reliable measurements in daily practice. They are largely handmade by experienced workers, and are checked for tight tolerances in weight, optical quality, durability and for consistent measurement results.
As supplier of complete solutions, Haag-Streit offers a wide range of accessories of great benefit to the ambitious slit lamp user.
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.
The use of this eyepiece ensures perfect focus of the microscope image onto the camera by compensating for user accommodation.
The eyepieces for length and angle estimation provide a reticle in the optics which gives a reference for linear distances and angles. The eyepiece with reticle for both length and distances comes with 10 x magnification and requires an adapting sleeve for BQ / BP 900 since it has been developped for the BM 900.
The eyepieces for length estimation provide a reticle in the optics which gives a reference for linear distances. The eyepiece comes with 12.5 x magnification and fits directly into the BQ / BP 900.
This eyepiece provides a reticle in the optics which shows a grid with different density pattern. These pattern allow the observer to estimate the cell density of the endothelium. It is recommended to use it in combination with the contrast enhancing 2.2 x contact lens to provide enhanced viewing of the endothelium.
A bright and even background illumination is an important factor for all imaging applications on the slit lamp. All LED illumination heads for BQ 900, BP 900 and BI 900 are pre-configured so that only the fiber optic need to be connected. Haag-Streit offers two solutions: A pivoting background illumination which has the advantage that it can be set independently from the slit illumination and a fixed version which has the advantage that it does not restrict the operation area between slit lamp and patient.
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.
With the BQ 900 it is possible to add video or digital cameras to the beam splitter with two different C-mount adaptors, which offer different focal lengths for variable sensor sizes. A f56 adaptor which is recommended for 1/3" sensors and a f75 adaptor for 1/2" sensors. Both adapters include aperture control which allows to control the depth of field within the image.
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.
This accessory mounting base is a standard interface for attachements to the slit lamp such as laser adapters or applanation tonometer.
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.
