Technology for Polarization Measurement

Mid Field Imager


The newest system to the Hinds Instruments Birefringence Measurement catalog, the Mid Field Imager is designed for high speed retardance measurement of a variety of samples. Where Exicor systems have been limited to planar samples only, the Mid Field Imager offers strain imaging of any free form optic, glass, plastic or biological sample, as well as standard planar samples up to 148mm x 130mm. Along with the new ability to measure free form samples, the Mid Field Imager is also the first wireless system from Hinds Instruments.

Useful for academics, research and development, and quality assurance, the Mid Field Imager provides users with quantitative stress measurement of samples within seconds. The Mid Field Imager's polarization imaging will give the same ease and feel of using cross polarizer analysis, while also producing quantitative data with its easy to use software.
