Real-time polarimeter for fast and precise measurement of the stress birefringence in large-format transparent materials and components
Internal stresses affect the mechanical and optical properties of products made of glass and plastics, both in the manufacturing process as well as in the further processing.
With the StrainScope Stepper you can measure residual stresses with high spatial resolution precisely and reproducibly. The telecentric optics enable the measurement of even thick materials without parallax errors and the measurement of residual stresses in materials with intrinsic birefringence, e.g. sapphire, calcium fluoride or silicon carbide.
The motorized positioning stage enables automatic stitching of larger samples up to 220 x 220 mm², e.g. lens blanks for high-end optics or SiC wafers for the semiconductor industry.
