B&L Stereozoom 7 Objectives



Since Ed mentioned his Stereozooms, I would like to know if anyone has a source for an objective lens pair (it seems to be a single piece) for a Stereozoom 7. The one I got looked dirty; I tried cleaning it, but no good. I then removed the lens to clean the rear of the glass, but it turns out that the front surface has a matte finish! I don't know what could have done it, since there are no obvious deep scratches. I still am able to use the scope, but there is a haze to the image, and the detail, of course, is crap (so now I'm using my old B&L Stereozoom 3). I really like this instrument, and would like to be able to use it again. A lens off of a "parts" machine would be fine, or a NOS lens would do, as well.

BTW, I wondered if the lens clouding could be due to a fuming acid, or other noxious stuff, but there seems to be no damage to the rest of the underside of the scope - just the glass.

Thanks,
Joe
