Handheld strain viewer, with no limit to measuring height, is an innovation from Suzhou PTC Optical Instrument Co. Ltd. Designed to detect internal stress distribution in transparent glass and plastic products, our Polariscope (Model No: PSV-202-D) offers a viewing field of 200mm*200mm and a measuring height of 236mm.

The sensitive color detection method, along with a full-wave plate retardation of 560nm, ensures accurate stress analysis. This machinery, weighing 8KG, operates at 24VDC with an AC/DC adaptor.

Suitable for a range of products like penicillin bottles, mobile phone covers, and crystaline materials, our Polariscope aids in evaluating and improving the annealing process.
