产品描述
The instrument:
?
Transparent objects due to uneven cooling or other mechanical effects and other reasons, the internal stress, induced birefringence. Optical characteristics of crystal material itself has double refraction. WYL-4 stress birefringence instrument using photoelectric polarization vector synthesis and optical compensation principle, the difference of optical path through the quantitative determination of samples, determine the stress birefringence of the samples. To determine the stress level of optical glass optical path the instrument can accurately measure the optical wave plate, optical instrument manufacturing, instrument is indispensable, it is also an important tool to study the crystal minerals.
With the instrument.? :
?
Stress instruments are used to check the stress distribution and size of transparent objects. Not only has been widely used in optical glass, optical instruments, glass products, plastic products and other industries, but also plays an important role in the inspection of building materials, lighting, pharmaceutical, beverage, handicraft safety index, there are many applications in crystal jewelry production, geology, material science field. At the same time, the teaching experiment equipment of this instrument is one of the colleges and universities special ideal.
