Description: Both the American Optical ca. 1950 Catalog of Microscope Accessories, page D-4, and the AO “Red Book” published in 1958, describe this lens as follows: “The reflecting objective has been developed for spectrophotometric work in the ultraviolet and infrared bands of the spectrum where systems using conventional glass lenses do not function. This objective, a spherical catoptric system, is completely achromatic. It can be used with minimum refocusing in the extreme ranges of ultraviolet or infrared and is especially useful in the lower limits where its ability to transmit light is relatively high.”50X magnification powerNumerical Aperture 0.56Lens comes with its original AO velvet-lined case with snap closure; case is in excellent conditionAlso included is the original protective objective dust capLens has standard RMS mounting threads Lens is optimized for 160 mm tube length optical systemsLens is not optimized for infinity corrected optical systemsMade in the U.S.A. by the American Optical Company AO “Red Book” lists the price of this lens in 1958 at $235.
