Product Description

The handheld Polariscope ( Ref.PSV-202-D ) has been designed to cover a wide range of strain viewing applications.
It can be applied to the quality control inspection of glass and plastics components and may be employed as a vertical or horizontal viewing instrument.
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 to carry .
The working space available within the unit enables a wide variety of components to be accommodated for hand held examination under polarizing light., such as fish tank.

Detecting object
1. any transparent glass products
such as : fish tank , mobile phone cover, lighting tube, solar glass ,automobile glass,sapphire, glass container , glass handicraft
2. any transparent plastic samples
such as : plastic bottle , cosmetic bottle , beverage bottle, plastic tray, plastic film

3. Crystaline material

Specifications
Optical retardation of full-wave plate : 560nm
Viewing field ( illuminating area ): 200mm*200mm
Analyzer( on the top ) : diameter 100mm
Overall size:300mm*300mm*80mm
Voltage: 220VAC
Light source: White LED lamp
Weight: 4.5KG

Measuring Principle
The internal stress of glass and plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from he polarized lamp will be divided into different units, which produce optical interference phenomenon(ripple patterns) in turn.
Under white-light lamp, you can see aubergine ripples, which is caused by the presence of stress.
From the observation of colored patterns, you can see stress distribution directly, then evaluate and improve the annealing process.
The inspection of plastic molds is more complex as the colored patterns cased by stress is irregular. A similar situation may occur with glass products, which is called stress stretching. For example, a qualified mold will have a large amount of stress released by tension.
