Cossed Nicol 法检测
Crossed Nicols 法观测应力，整个视野将出现黑色。样品置于观测台，存在应力的部位为明亮的白色，没有应力的部位将呈现黑色，和未置样品时同样的黑色。其中，变为蓝色、绿色、红色等颜色的位置，是应力比较多的集中区。

＜Application＞
・Existence or nonexsitence of strain for glass product

Semiauto Senarmont PTC-702is the instrument for visualizing strain in transparent medium and measuring its degree.This product displays the image brightness amount in figures in the monitor,and according it simplifies looking for Analyzer rotated angle where the target area blacken to the maximum. This system reduces the measurement error caused by an operator.
It also has Sensitive color method,so it is available to confirm the direction of the stress.
It is available to record the measurement data and image since it it connected to PC.
Features：Reduce measurement error caused by an operator,Calculate the degree of glass stress by being entered photoerastic constant and optical path in advance,Make report easily by saving data and image in PC,Change the monitor magnification from about*1to *24(Using 15.4 inches,1280*800 dot LCD monitor)
Apprication：Strain Inspection for glass,Strain Inspection for plastics,Measurement of the retardation of optical film.etc.
