Photonic Lattice 2D Birefringence Measurement System WPA-200Series

Suitable for measurement of films and transparent resin products

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.
Ranging from microscopic to macroscopic (～50cm), the field of view adapts to any measurement situation, and there is a system for each size.
