Abstract
A magnifier for observing a surface includes a housing, a detachable window attachment coupled to a first end of the housing and an eyepiece coupled to a second end of the housing. A light source attachment is coupled to the housing for supplying light to the hollow interior of the housing. The light source attachment and housing each have major axes which extend in different directions and form an angle between approximately 110.degree. and 120.degree.. Photoconductive material serves as a light guide for directing the light from the light source attachment to the window attachment.
