Description

Vintage Bausch and Lomb 4 objective microscope with illuminator and dimming transformer(tested working)
sold as is for restoration or parts- I do not know much about these so I have not tested anything other than he light/ transformer- that dims as it is supposed to
all knobs move smoothly and raise/lower the scope and the bed and slide holder moves front / back and left / right
4 spaces for lenses but one is empty
b&L 32mm 0.10
b&l 0.25 N.A 10x 215mm
Karl Zeiss UD40/0.65C  0.17
eyepiece lens slides out but has threads on the end so I am not sure if there is a missing internal piece in the neck for it to screw into...? Seems to me that eh eyepiece would screw in and out to adjust for eye relief but it just sits in there.
