1. What is the application of the 600,000 lux illumination clinically
   The 600,000 lux, we believe, is the brightest level of illumination currently available from any slit lamp. When viewing the eye through a small (optical section) slit it will provide the highest level of illumination and therefore detail. This is one of the main reasons why Haag-Streit sli ...
2. What is the use and clinical application for the short mirror
   The short mirror is generally used when the slit lamp illumination column is tilted forward. In this position only the bottom section of the mirror is used but the top ('neck') of the mirror can obstruct the view through the oculars when illumination is coaxial. This type of arrangement is ...
3. Why does Haag-Streit use a slit of 8 mm
   The 8mm slit issued for very good reason. The optics of the illumination tower are such that at 8mm our light patch over the complete circle is homogeneous and absolute measurements of area and length can be made in any orientation. Furthermore as the 600,000 lux illuminance level available on m ...
4. Can I use a Halogen bulb on the BQ900
   Yes. A halogen lamp is available for the BQ but we do not recommend it. The output from our tungsten bulb is 600,000 lux - brighter than any other slit lamp on the market. Some of our competitors, such as Topcon, offer halogen BUT doctors are also advised to use a filter to make the light less b ...
5. Why should I purchase the CM900 or IM900 rather then a consumer camera
   Using a consumer camera is less expensive but not necessarily a simple method of slit lamp imaging. If it was simple then we would have had no need to develop the IM or CM cameras and everyone would be using consumer cameras. The lens systems on consumer cameras make the integration with the sli ...
6. Why is back ground illumination considered essential
   There are two major reasons why imaging slit lamp should have a quality background illumination system: - Overview images: for this the diffuser will work but using the background illumination and slit beam (diffused) will produce a shadow free illumination with natural colours and two light ref ...
7. The BQ with IM 900 seems very long
   The length of the system can be reduced slightly by using the CM 900. The CM900 with a Beamsplitter (44mm) is 24mm shorter than IM900 (68mm).
8. Can I connect the Nikon D40 to the BP900
   The Nikon D40 cannot be used with the BP. The SLR cameras generally have a larger chips size than the 'point and shoot' type of cameras and the light would be reduced too much if we were to make optics to match this. Our choice of camera would be the new CM900 which is a 1.3MP camera that gives ...
9. Can I connect CM900 to my BC900
   This is not possible, only mini mount cameras like the Toshiba can be fitted. Upgrade from the BC900 to the BD900 would not be economical as we need to replace the microscope as well as the microscope arm.
10. Can I upgrade my PB-Q to a BX900
    It is possible to upgrade the old version of the photo slitlamp PB-Q900 to the new digital photo slit lamp BX900. The BX900 allows you to capture high resolution images (8 million pixels) using the Canon EOS technology. Recommended camera at the moment is the Canon EOS 40D, but different adapter ...
11. Can I upgrade my PB-Q with a digital camera back?
    Yes, an upgrade the PB-Q to digital is possible however we have seen problems with the very old control unit. Upgrade on this is trial and error. Old units may accidentally flash. Upgrade of the later photo control unit (part 1400030) should work. Requirement from HS: -The remote control cable, ...
