Stereo-variator 900.5.7 for Haag-Streit BQ slit lamp.
The stereo variator for the BQ 900 slit lamp reduces the 13° angle to 4.5°. Thus, an enlarged binocular field of view is possible even with myopia or through small pupils. This also aids the observation, without additional lenses, of the peripheral fundus and vitreous.
