BQ 900 LED

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.

Optical excellence

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.

Sophisticated microscopy

Stereo variator

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.

Sophisticated microscopy

Zoom objective

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.

Yellow filter

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.

Sophisticated microscopy

Beam splitter

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.

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.

Imaging solutions

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.

Imaging solutions

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.

Imaging solutions

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.

Imaging solutions

Intuitive software

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.

Imaging solutions

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.
