2D Birefringence Measurement System

WPA-200Series

WPA series that expands the measurement range of phase difference from 0 to 3,500 nm by measuring the distribution of birefringence/phase difference over three waves.
Suitable for measurement of films and transparent resin products.
Ranging from microscopic to macroscopic (～50cm), the field of view adapts to any measurement situation, and there is a system for each size.

WPA-KAMAKIRI

This product is very effective if evaluation with high spatial resolution is essential.With the WPA series, it is possible to measure a phase difference of about 3000 nm by selecting three different wave lengths and comparing and calculating the phase difference at each wave length.

PA-300Series

PA series measures birefringence and phase difference with high resolution of 5 million pixels at high speed, for low phase difference with a measurement range of 0 to 130 nm.
Suitable for measurement of glassware and other low phase difference targets.

WPA-300Series

The WPA-300 series provides sharper measurement by increasing the resolution of the polarization image sensor up to 5 times, while maintaining the large phase difference measurement performance of the WPA-200 series.

PA/WPA-NIR Series

By using the near-infrared band for the measurement wavelength, this system can measure birefringence/phase difference distribution even for materials that are opaque to the naked eye. Suitable for measurement targets that transmit near-infrared wavelengths, like chalcogenide lenses, LiDAR automotive components, etc.

Birefringence & Stress Strain Measurement

We have improved conventional birefringence measurement from point measurement to 2-D surface measurement. High-speed, high-precision birefringence measurement contributes to quality evaluation and functional improvement of optical materials.
