YLY-05 Polarization Stress Meter Introduction: The YLY-05 digital polarization stress meter is suitable for pharmaceutical enterprises, glass product factories, and laboratories to measure the stress values of optical glass, glass products, and other optical materials. The instrument can qualitatively and quantitatively test the internal stress of glass, and the results are automatically read on a color LCD screen. Features: 1. There are two experimental modes, qualitative and quantitative, with adjustable experimental space and wide applicability 2. High precision absolute angle encoder is used for measurement, with a measurement accuracy better than 2.0nm 3. A 5-inch color LCD screen that can simultaneously display the measurement angle and optical path difference values, making the measurement intuitive and easy to read 4. The dark field of view does not require calibration and uses an absolute encoder. The polarization field of the dark field of view is always at the zero angle point, so there is no need for users to calibrate the zero point, avoiding errors caused by manual calibration of the dark field of view 5. Equipped with a micro printer for easy printing and output of test data Technical parameters: Instrument reading: 0.1 nm Measurement accuracy: 2 nm Polarization field diameter: 150 mm Picking up polarizer rotation angle: 360 ° Edge brightness of light field: ＞ 120 cd/m ² Adjustable range from polarizing mirror to polarizing mirror: 280 mm Luminance of the light field: ≥ 800 lux External dimensions: 220 mm (L) x 310 mm (W) x 580 mm (H) Power supply: AC 220V 50Hz Net weight: 8 kg
