Polariscope

Experimental And Demonstration Polariscope It is placed on an overhead projector (not supplied), with the image projected on to a screen, and, used either in a laboratory or a lecture theatre, allows a striking demonstration of the stress fields in the loaded models. It is also designed for quantitative work for tensile, compressive or flexural loading. A system – unique to this unit – also allows the simultaneous rotation of the polarizer and the analyser for the isoclinal lines study. The Polariscope consists of the following elements : A model-loading frame. An elastic load-measuring device, which uses a steel spring beam, and a micrometer dial gauge. Thedevice has a linear deflexionload relation-ship. A rotatable circular polarizing unit, in a graduated mount, carried on runners under the loading frame.
