Brief Description: The first metal McArthur miniature microscope, made in 1932 following trials with a wooden prototype. The optical components are contained within a chromium plated housing. The eyepiece is situated at one end of the instrument. Two spring clips on top of the housing hold specimens over an opening. A condenser mounting is held on a hinge over this position. Below is a dovetail slide that can carry three objectives and light is refracted thought right angels, by two prisms, to the eyepiece. Two milled knobs on the side of the housing focus the light.
The McArthur microscope was invented in 1930 by John N. McArthur (1901-1996). It received a Council of Industrial Design award in 1970. A plastic version is used by students of the Open University (see 13297 and 42214).
