Equipment | Optical Inspection |Polariscopes


A polariscope is an optical inspection device used to detect internal stresses in glass and other transparent materials such as plastics, synthetic resins, etc. A polariscope is composed chiefly of a light source and two crossed polarized lenses. The polariscope light source is mounted beneath one lens, and is powered by either self-contained batteries or an external power source. Material to be examined is placed between the two polariscope lenses and viewed through the lens opposite the light source lens.
