2D Birefringence Measurement System

WPA-micro

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

Predict with FOV of microscope.

The included microscope can be selected either Olympus or Nikon.

Evaluation of crystal orientation distribution

Crystal orientation distribution can be datamined in the microscope FOV.
Reflection measurement of opaque samples such as metals is also possible.

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.

PA Series PA-micro / PA-micro-S

This equipment 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. A type that can measure birefringence with microscope FOV. The included microscope can be selected either Olympus or Nikon

WPA-200-MT

A series that expands the measurement range of phase difference from 0 to 3,500 nm by measuring the distribution of birefringence/phase difference over 3 waves. Separable light source which can be incorporated into inline and measurement stage.

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.

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.
