 Glass stress instrument (superior products) Model: M31NJW11SZY150A (China) library number: M295280 


 Product Manual 

 First, the purpose and scope: 
 This glass polarized stress tester is the application of stress within the glass interferometry inspection equipment. As a result of sensitive color film, the instrument can be polarized field in the interference color sequence of qualitative measurements, the stress within the glass, the apparatus for glass, Glassworks Glass residual stress test.

 Second, the main technical indicators: 1. Polarizer aperture? 150mm 2. 48mm diagonal polarizer glasses Third, qualitative detection principle: in the orthogonal polarizer and the analyzer microscopic mirror placed between the unit under test ( birefringent material), there will be further field of color, a certain degree of interference color corresponding to a certain degree of birefringence in the optical path difference, the relationship shown in Table (a) shows, no test pieces, the universe into a purple field. Fourth, the measurement methods: 1. Hand-held: instrument factory, the polarization field has been adjusted, use hand-held rotating polarizer and analyzer optical chip to purple field. Further into the field test conditions, the human eye can observe the entire surface of the device under test, according to qualitatively determine the interference color quality of the specimen annealing. 2 desktop, before use hand-held piece hanging from the light box on the side, through the glasses can be observed from the side piece of purple, you can put into test pieces. If the test piece in the interference field, the color will remain basically unchanged (still purple) shows annealing of good quality. If the specimen interference color changes on some parts of the larger (for example: green or yellow) shows annealing of poor quality. Fifth, note 1 instrument The instrument used to moisture, dust, corrosive gases, they will not use trade good. 2 other pieces of the optical instrument may not touch or rub the surface, where dust can be used silk cloth and gently wipe. 3 instrument should be gently, to prevent the fall, hit.
