Strain Viewer fortransparentglass and plastic

(Ref.PSV-202)

The Strain Viewer ( Ref.PSV-202) has been designed to observe and analyze the internal stress of transparent glass and plastic products .

Components : LED light ,a polarization analyser, a polarizer

 

Application:
 
  • To detect transparent glass products with complex construction.

such as : penicillin bottle, ampoule ,mobile phone cover, lighting tube,solar glass ,automobile glass,sapphire, glass container , glass handicraft  

2. To detect transparent plastic samples

plastic bottle , cosmetic bottle , beverage bottle, plastic trayplastic film

 

Specifications:

Detecting range : 0-280nm

Optical path difference of full-wave plate : 560nm

Viewing field: 200mm*200mm

Measuring height:236mm

Overall size:300mm*280mm*330mm

Voltage: 220V

Light source: white fluorescent lamp

Weight:8KG

 

Principle:

The stress of glass and plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light fromhe polarized lamp will be divided into different units, which produce optical interference phenomenon(ripple patterns)in turn.

Under white-light lamp,you can seecolored ripples,which is caused by thepresence of stress. 

From the observation ofcoloredpatterns, you cansee stress distribution directly,, then evaluate and improve the annealing processes.

The inspection of plastic molds is more complex as the colored patterns cased by stress is irregular. A similar situationmayoccur with glass products, which is called stress stretching. For example, a qualified mold will have a large amount of stress released by tension.

The role of full-wave plate :



When testing glass samples without the full-wave plate, usually only black or gray shadow patterns can be seen. The full-wave disc increases or decreases the full wavelength of a phase difference, thereby forming a colored pattern, which is easier to analyze.
