Polariscope detecting stress in glass and Quartz products

 (Ref. PSV-413)

Function

1. Observe stress distribution in transparent plastic, glass products and optical crystals

2. Measure retardation caused by internal stress in glass and optical crystals

Detecting object

1. transparent glass products with complex construction.

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

2. transparent plastic samples

plastic bottle , cosmetic bottle , beverage bottle, contact lenses, plastic tray， plastic film
3. optical crystals such as quartz , SiC, calcium fluoride

Detecting methods

Sensitive Color Method and Senarmont Method

Specification

Others:

1. Polarizing light field intensity : ≥ 120cd/m²  (10W LED lamp)

2. Polarization degree of the polarizing material: ≥ 99%

3. Polarization field: 200*200mm

4. Instrument structure: a 1/4 wave plate in the analyzer and a full-wave plate in the polarizer (wavelength 565nm). Slow axis of the plate is at 90° to the polarization plane .

5. A dial on the Analyzer is used to measure the rotating angle (range: 0-180°)
