Sophisticated microscopy and LED power for more detail
Thanks to its sophisticated design and excellent optics, the BQ has become the standard for any advanced Slit lamp Bio-microscopy. The 5-step Galilean magnification changer gives the user a range of 6.3x all the way to 40x with steps in between of 10x, 16x and 25x. The high light transmission and optical quality, together with the large ocular field of view, ensure a superb clinical view and allow for a more comfortable examination. A wide range of accessories can be added to the BQ Slit Lamp, such as the Inclined Adapter and Stereo Variator.
The addition of the Imaging Module, IM900 (optional) provides the user with superb digital Imaging even under difficult light conditions. Like any professional camera, the IM900 is equipped with depth of field control, allowing to adjust the camera for the ideal image, regardless of the pathology.

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.
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.
Inclined eyepiece adaptor
With the inclined eyepiece adaptor, the view into the microscope is inclined at 20 degrees to the horizontal. Consequently, the examiner is able to maintain his head in a fatigue-free position.
With the zoom objective, the magnification can be continuously changed from 6 up to 40 x. Reference points are set at magnifications 10 x, 16 x and 25 x to allow easy orientation. The zoom objective offers excellent diagnostic capabilities – especially when used in conjunction with video function. Any existing BQ 900 can be modified from a standard model to a BQ 900 – Zoom.
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.
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.
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.
Intuitive imaging – best results
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.
IM 900 - outstanding image quality
Equipped with an ultra-sensitive camera, the IM 900 produces images of exceptional quality even under difficult light conditions. Thanks to this sensitivity patient comfort is improved significantly as it is easily possible to record findings without excessively dazzling the patient. Like any professional camera, the IM 900 is equipped with depth of field control, which allows to adjust the camera ideally, regardless of the location of the pathology.
Ideal workflow – no distraction
The control panel allows to operate both the camera and the slit lamp illumination. Located in front of the joystick of the slit lamp, it can be used blindly while focusing on the patient. The compact and modern design conforms to the design of the slit lamp. Thus the Imaging Module comes as a component of the whole system, thereby supporting an ideal examination workflow.
Simple image capturing
A fast and accurate automatic exposure control ensures correct illumination of the image while the operator is concentrating on his examination. Thanks to the History Trigger function, there is no need to worry about a patient blinking or moving when taking an image. The History Trigger does not just capture a single image, but records the last few seconds in real time and allows to select the perfect image.
EyeSuite Imaging is a straightforward imaging software supporting the Haag-Streit imaging solutions. Easy image capture, efficient image editing and a well-structured patient management system make the software a perfect team player for daily practice.
Flexible interfaces for easy network integration
The EyeSuite software is designed for optimal patient flow in busy practices. Supporting the Haag-Streit imaging solutions, EyeSuite makes the slit lamp fully networkable. Thus, no proprietary third-party software is required to provide connectivity. If the slit lamp is connected to an EyeSuite server, all the images taken can be accessed remotely from any number of viewing stations connected to the same database.
More convenient than ever before
The Imaging Modules IM 900 and IM 600 are more than just cameras. They are fully integrated compact imaging solutions providing features which make slit lamp imaging more convenient than ever before.
The Goldmann tonometer
The Goldmann tonometer is a powerful accessory for the 900 series slit lamps. The Applanation Tonometer is the most widely used instrument to measure interocular pressure. It allows IOP measurements to be taken with the patient at the slit lamp as part of a routine examination.
Disposable tonometer prisms
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.
Excellent optical quality
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.
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.
Eyepiece with crosshair reticule
The use of this eyepiece ensures perfect focus of the microscope image onto the camera by compensating for user accommodation.
Eyepiece for length & angle estimation
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.
Eyepiece for length estimation
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.
Eyepiece with McIntyre comparison grid
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.
Video adaptor for digital cameras
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.
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.
Accessory mounting pin
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.
