A lens mount for a microscope objective comprising a correcting ring, which is used for moving a part of lenses constituting the objective along the optical axis in order to correct deterioration of the image, and a friction band arranged round the outer surface of said correcting ring and made of material such as rubber so that said correcting ring can be easily rotated by rubbing said friction band by a finger bulb.
Claims2
A lens mount for a microscope objective comprising a correcting thin ring for moving a part of lenses constituting the objective along the optical axis for the purpose of correcting aggravation of aberrations caused by variation in thickness of cover glasses, and a friction band arranged round the outer surface of said correcting ring for finger bulb movement of said ring and made of soft and frictional material such as rubber, said microscope objective being used by mounting to a revolver closely spaced to other microscope objectives which necessitates said ring being thin and being arranged to correct aggravation of aberrations by moving said part of lenses by rotating said friction band.
