Digital Polarization Stress Meter For Glass Internal Stress

Description

YLY-05 digital polarizing stress meter is suitable for measuring the stress value of optical glass, glass products and other optical materials. The glass stress measurement equipment can qualitatively and quantitatively measure the internal stress of glass and automatically display the result on the LCD screen.

There are two models for this polarizing stress meter has 2 models,including no built-in printer and built-in printer that can automatically print data when the test is completed.

Features:

• Qualitative and quantitative both test modes, test space adjustable, wide application.
• High-precision absolute angle encoder for measurement, the measurement accuracy is better than 2.0 nm.
• It can display the measurement angle and optical path difference value at the same time, making the measurement intuitive and easy to read.
• The dark field does not need to be calibrated due to an absolute encoder is used.The dark field of polarized field is always at the zero angle point, so there is no need for the user to calibrate the zero point, avoiding the error caused by manual calibration of the dark field.
• Equipped with a micro-printer, easy to print out test data.

Principle:

An instrument for determining internal stress in glass or birefringence of crystals based on the principle of polarized light interference. The polarization stress meter is equipped with a sensitive color plate and applies the 1/4 wave plate compensation, hence the instrument can not only qualitatively or quantitatively measure the optical path difference of glass according to the interference color sequence in the polarization field, but also measure the thickness of the glass with the wall thickness. It can measure the internal stress value of the glass accurately and quantitatively.

Application:

In the wholesale crystal and jewelry industry, it is very necessary to have a polarizer, such as this website  wholesalecrystalsupplier.com has purchased our polarizer. The digital polarizer is a simple and high-precision gem identification instrument, which can be used to detect the optical properties of gemstones, judge the axial properties of gemstones, and optical symbols and check the multicolor of gemstones.

Suitable for polarized internal stress testing of glass infusion bottles, glass tube (molded) medicine bottles, tube (molded) injection bottles, ampoules, oral liquid bottles,
Glass containers such as beer bottles and liquor bottles.
