Quantitative stress detector 3 specifications:
, polarized stress meter light field brightness
. The degree of polarization at any point of the polarizing element of the polarizing stress meter is greater than or equal to 99%
The polarization field of this stress meter*
. The structure of the polarizing stress meter: analyzer and polarizer A wave plate and a full-wave plate (with a wavelength of ) are respectively placed between the mirrors. The slow axis of the wave plate is aligned with the polarization plane of the polarizer
. There is a rotation angle measuring device (scale) on the top of the analyzer. The value is in degrees, the maximum measurement range is in degrees)
Quantitative stress detector 3 detection method:
.-Photosensitive color method detection
Photosensitive color method measurement, the entire field of view is reddish-purple, this Each color is divided into photosensitive colors.
Put in the sample, and the areas with stress will appear green-blue or orange-yellow. and determine whether the nature of the stress is pressure or tension.
The sample parts without stress are reddish-purple.
.Compensation method
The compensation method can perform quantitative analysis and detection of stress. Turn on the power, and the entire field of view before placing the sample will be dark brown. Put the sample in, and do not rotate the analyzer. The brightest point observed is the point of maximum stress. Rotate the dial on the analyzer until the brightest point turns dark brown. Record the angle of rotation of the dial at this time and the thickness of the point. You can use the formula to convert the stress value.
