As the newest in the Haag-Streit series of quality slit lamps, the BI 900 contains an enhanced illumination system and improved microscope with Haag-Streit high-precision mechanics in a simple and reliable system.
The BI 900 has default magnifications of 10× and 16×, but can be extended to 25× and 40× magnification with an optional set of oculars. Additional contrast can be provided by a yellow barrier filter for flourescein application examinations. The diameter size of the ocular view has been increased to reduce fatigue during examination.
Can be purchased with the optional BI 900 imaging set.
