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.
