Abstract
The utility model relates to the improvement of an ordinary optical microscope. The utility model is characterized in that an optical bench is additionally arranged on an objective table of an ordinary optical microscope. A collecting lens and a light source lamp are arranged on the optical bench. Under a high power objective, a slide with a cylindrical surface or a slide with an inclined surface are changed to use. Light rays ejected by the light source lamp are refracted by the collecting lens, and are concentrated on an observed sample; after refracted by the surface of the sample, the light rays enter a light path system to amplify and form an image. The microscope uses an ordinary optical tool to substitute a valuable beaming light source of the valuable stereomicroscope, has the advantages of low cost and convenient use, and has double purposes of a transmitted light microscope and a reflected light microscope.
