2D Birefringence Measurement System

WPA-200-MT

A series that expands the measurement range of phase difference to 0 ～ 3,500 nm by measuring the distribution of birefringence/phase difference over 3 wavelengths.

Separable light source so the measurement head can be incorporated inline into production line.

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.

PA-300-MT

High-speed, high-resolution measurement of birefringence/retardation targeting the low measurement range (0～130nm), for example glass, optical lens, etc.Separable light source which can be incorporated into inline and measurement stage.

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.

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.
