The Strain Viewer (Ref.PSV-201)has been designed to cover a wide range of strain viewing applications.It can be applied to the quality control inspection of glass and plastics components and may be employed as a vertical or horizontal viewing instrument.The working space available within the unit enables a wide variety of components to be accommodated for hand held examination in polarised light. The Strain Viewer incorporates a light source, an analyser with quarter wave plate and a polarising element with quarter wave plate. For the strain viewing of glass and acrylic components, a full wave plate have been incorporated in the optical system. Using scope: 1, To detect transparent glass products with complex construction. 2, To detect transparent plastic samples.
