Automatic Computerized Polariscope (Ref :
NMV-145)
This full-auto Polariscoper is a stress measurement device that automatically detects the optical path difference and the slow axis direction of transparent object
s which displays
birefringence phenomenon under polarized light.
When light
travels through the polarizer, it
becomes circular polarized light. When a stressed sample is placed, there is an
optical path difference between
the slow axis and fast axis . A
nd the outgoing light becomes elliptical polarized light. By rotating the analyzer
, the rotating angle
of
the polarized light which
is affected by the presence of internal
stress can be detected precisely
. By applying the rotating angle to a formula, stress value in
the sample will be calculated
. During one measurement, this full-auto Polarimeter
can take images at a specialized
angle, and simultaneously obtain the stress size and slow axis direction of all sample areas in the viewing field
and output the three-dimensional stress distribution.
The camera connected with a computer, detecting data and images can be stored easily .
The light source adopts high-brightness LED light, which has a long service
life and low
electricity consumption . In this way , time and operating cost of replacing the light source will be decreased .
Features
1. One-key automatic stress measurement within
the whole viewing
field ;
2. The axial direction of the stress at each point can be displayed
together with the internal stress
value, which is convenient for
stress type analysis;
3. The result is displayed in 3D mode, which visually displays the stress level of each point;
4. Use background light calibration to eliminate environmental errors;
5. The high-speed and standard measuring
modes can be switched freely to control detecting speed;
6. Using
area array LED
light source, the brightness difference between center and edge is ≤20%;
