Transmitted Light Polariscope

Photoelastic analysis is achieved by passing light through the mechanical stress models while a tensile load is applied. The frame has the Transmitted Light Polariscope filter and quarter wave plate mounted to rotational frames. The Transmitted Light Polariscope is a bench top mounted frame which allows the study of stress patterns and photoelasticity resulting from geometrical changes in loaded mechanical models. Transmitted Light Polariscope can be vertically or horizontally mounted onto the light box. These frames allow the rotational angle of the plates and filters to be adjusted and hence vary the colourisation seen by the user. Rubber mounting feet enable it to sit firmly onto the light source. The frame can sits in front of a light box which supplies monochromatic or white light.
