Stereo-variator 900.5.7 for slit lamp Haag-Streit BQ.
Uniquely with the BQ 900® an optional stereo variator 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.
It improves fundus viewing for imaging applications.
