Easy-to-carry glass Polariscope with light weight

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

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.
