Description

Technical Field

[0001] This utility model relates to the field of stress testing technology, and in particular to a detachable multicolor polarized stress meter. Background Technology

[0002] A polarimeter is an instrument used to detect the internal stress distribution of transparent or translucent materials, primarily for quality control and research of materials such as glass and plastics. It utilizes the polarization properties of light and the birefringence phenomenon that occurs in materials under stress to detect stress.

[0003] When light passes through a transparent material with internal stress, the different refractive indices of different parts of the material cause the light to be deflected to varying degrees, a phenomenon known as birefringence. This effect alters the vibration direction of the polarized light after it has passed through the material. By using a polarimeter, interference fringes (usually colored fringes) caused by stress can be observed. The distribution and color of these fringes reflect the magnitude and distribution of stress within the material.

[0004] The prior art CN210426839U discloses a foldable portable polarizing stress meter, including a main body, a folding cover, an observation plate, a light source window, an observation window, and a damping hinge.

The light source window is fixed to the middle of the main body, and the observation window is fixed to the middle of the observation plate. The outer diameter of the observation plate is less than or equal to the inner diameter of the folding cover, so that the observation plate can rotate and embed into the folding cover. The folding cover rotates and abuts against the main body. A magnetic switch is fixedly connected to the end face of the main body that abuts against the folding cover.
