Brief introduction: Wyl-150a polarizing stress meter is an instrument that USES polarizing light interference principle to check the internal stress of transparent glass body or the birefringence effect of crystal. Because the instrument equipped with incandescent light, natrium, sensitive piece (full wave plate), and application of 1/4 wave plate compensation method, so the instrument can not only according to the interference color sequence in the polarization field qualitative or half quantitative measurements of the glass and the internal stress distribution of can accurate quantitative numerical, measure the internal stress of glass instruments for optical factory, glass factory, glass factory, laboratory, measurement of optical glass, glass and other transparent body materials stress value, is not only widely used in industrial production, and in the defense, building materials of geology and mineral materials, science is also important, At the same time, this instrument is also an ideal education experimental equipment for colleges and universities. Main technical parameters: Optical path difference measurement range: 0-589.44nm Measurement accuracy: plus or minus 4nm Phi with a diameter of 150mm polarization field Full-wave plate wavelength: 565nm The workbench rotation Angle: 0-360 ° Check polaroid dial scale: 2 ° Monochromatic wavelength sodium light: 589.44nm Incandescent light (halogen lamp) : 12V 25W
