Abstract
A miniature microscope is extremely small, fitting in a palm of a user's hand while providing powerful magnification and enhanced brightness so that the details of an object which cannot be resolved by an unaided eye can be easily seen. The microscope includes a housing have a holder for supporting an object to be viewed. At least one light source is position in the housing off-axis with respect to the object to be viewed. A first prism includes a first prism surface for reflecting light from the light source to a beam splitter surface wherein the beam splitter surface reflects light from the first prism surface to the object to be viewed. The beam splitter surface also passes light reflected from the object therethrough to a second prism. The second prism is positioned with respect to the first prism to provide refraction correction. The miniature microscope also includes a movable focusing optic that receives light passed through the first and second prisms for providing a magnified image of the object supported in the holder.
