Technology for Polarization Measurement

Exicor® MicroImagerTM

The Hinds Birefringence Imaging Microscope is ideal for measuring birefringence in biological structures (see Figure 1 below), glass, crystals, and many other organic and inorganic samples.


• No Dyes or Fluorescent labels required
• Measures retardation, angle and intensity
• Images retardation, angle and intensity
• Allows color maps to be customized by user for optimal display of data
• Allows maximum, average, and standard deviation over entire image and in user-selected areas or lines
• View data by intensity, birefringence/retardation, angle, or combination
• Histograms for statistical analysis
• User calibration
• Export of data in .csv and binary formats
• Export of data from user selected areas
• Export images in bit, png or tiff formats
• Compatability with third party analysis tool, ImageJ

Phase unwrapping technology is now included with every MicroImager.

→ For highly birefringent samples, the Exicor® MicroImagerTM has the ability to measure up to 3500nm with 4 color configuration and up to 2400nm with 3 color configuration.

In the mid-2000's, Hinds Instruments entered into an agreement with Cambridge Research and Instrumentation (CRi) to represent the LCPolscope® product line and later the Abrio® product line. After a series of business transitions, the Abrio product line was discontinued by Perkin Elmer. At the same time, Hinds Instruments introduced the Exicor® MicroImagerTM, which improved on CRi's liquid crystal technology using the Hinds Photoelastic Modulator (PEM) technology.
