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.
可快速自动测量应力双折射的大小、方向和分布
面测量、可一次测量视野范围内样品的全部数据
具备点、线、面、3D的分析功能
三波长可量测0-3500nm，可拓展至10000nm
可输出光程差（nm）、偏振角度（°）、应力（Mpa）、应力双折射（nm/mm）
