New Models of Binocular Micro- 

 scopes for Stereoscopic Vision 



Model "BSM" represents an entirely new design and 

 with its introduction we fulfill an urgent demand for an 

 instrument having low power magnification, extremely 

 long working distance which renders a magnificent 

 stereoscopic image of exceptional brilliancy. 



It is available in three different magnifications, 

 varying from 3.5 to lo.sX, with a free work- 

 ing distance of 140 mm. 



Eyepieces 3.5X render a field of vision so mm. diameter. 

 Eyepieces 7X render a field of vision 30 mm. diameter. 

 Eyepieces lo.sX render a field of vision 30 mm. diameter.
