Polariscope-Polarimeter PKS-250M
Polariscope-Polarimeter PKS-250M The device is designed to determine birefringence in flat workpieces and products made of transparent and lightly colored materials. Advantages and benefits: The device is used to quantify the magnitude of birefringence by the Sénarmont method, to evaluate the distribution of birefringence in an object by interference coloring, to study the distribution of birefringence in an object in circularly polarized light. A large viewing field allows you to control large-sized workpieces and parts, as well as simultaneous control of several samples. Manba: https://www.nv-lab.ru/catalog_info.php?ID=890
