There is a very cheap alternative, and that is the McArthur microscope designed for the Open University, It employs the same system as the original microscope but is larger in length & height 5" x 3" (127 x 76 mm.) but at 1" (25 mm.) only half the thickness. It is made almost entirely of plastic with a total weight of 7.5 ounces (198.5 grams). The standard Open University microscope has a fixed 10:1 eyepiece with a sliding objective plate with fixed 8:1 & 20:1 objectives. It has an internal light source or it can be used with an external lamp or daylight. There is a tripod adapter in the base. The specimen slide is held longitudinally and is therefore more easily controlled and is not likely to be moved by the fingers when handling the instrument.
not very powerful, but cheap. if you can find one. the "real" ones can do up to 100x oil immersion.
