Description

Technical Field

[0001] The utility model relates to the field of polarimeters, in particular to a multi-angle adjustable polarimeters. Background Art

[0002] Polarimeter is an instrument for measuring the optical rotation of substances. By measuring the optical rotation of samples, the concentration, content and purity of substances can be analyzed and determined. It is widely used in pharmaceutical, drug testing, sugar making, food, spices, MSG, chemical, petroleum and other industrial production, scientific research and teaching departments for laboratory analysis or process quality control. The optical rotation of optically active substances mainly depends on the structure of the substance itself. In addition, it is also related to the thickness of the light passing through the substance, the wavelength and temperature of the light used in the measurement. If the substance being measured is a solution, the influencing factors also include the concentration of the substance, and the solvent also has a certain influence. Therefore, the optical rotation of optically active substances is usually different under different conditions.

[0003] At present, polarimeters can achieve multi-angle adjustment when in use, and have semi-automatic functions, but they are often exposed to the outside, so their protection effect is poor. If they are hit by the outside, they are easily damaged, which affects their use. Therefore, we propose a multi-angle adjustable polarimeter to solve the above problem. Utility Model Content
