The Polariscope ( Ref.PSV-202) has been designed to observe and analyze the internal stress of transparent glass and plastic products . Detecting object 1. transparent glass products 2. transparent plastic samples 3. Crystaline material , Quartz

This Polariscope is designed to observe and analyze the distribution of internal strain in transparent preforms. It has been widely used in the quality control of various plastic rough processing products and finished bottles.

Different from common bench type Polariscope , this handheld Polariscope adopt seperating design , that means the analyzer and polarizer are movable . In this way , the net weight is almost reduced to half . This lightweight design make it more convenient

Polariscope detecting glass stress (Ref. PSV-413L) Function 1.Observe thermal stress distribution after annealing 2.Measure glass tempering grade 3.Measure optical retardation caused by thermal stress in glass Detecting object transparent glass prod

Different from common bench type Polariscope , this handheld Polariscope adopt seperating design , that means the analyzer and polarizer are movable . Viewing field : 400*400mm Analyzer（ on the top ) : diameter 200mm Overall size: 500mm*500mm*90mm

This Polarimeter adopts automatic Senarmont Method to measure the internal stress in transparent objects . This device automatically detects the image luminance, thereby finding the darkest point precisely
