Equipment

Composed of upper and lower polarizer and light source. In addition, it can be equipped with a glass carrier, interference ball and convex lens. The light source is usually an ordinary incandescent lamp. Sometimes a narrow window is opened in front of the polaroid light source box in an orthogonal position, which can also provide the light source for the refractometer. Polarizers are usually designed with lower polarizers fixed, and upper polarizers can be rotated to adjust the polarization direction. When natural light passes through the lower polarizer, the polarizer is generated. If the upper and lower polarizer are parallel, and all the polarized light from the lower polarizer passes through, the brightness of the visual field is the maximum. If the upper and lower polarized light direction is vertical, the polarized light from the lower polarizer is all blocked, at this time the darkest visual field, that is, extinction.
