Polarimeter for teaching experiment

Abstract

The present invention discloses a polarimeter for a teaching experiment. The polarimeter comprises an experimental box body which is internally provided with a half-wave plate which is embedded in the experimental box body. The half-wave plate is provided with bosses close to four corners. The bosses are clamped in the half-wave plate. The middle part of the half-wave plate is equipped with a light source. The bottom of the experimental box body is provided with a rotation rod. The top of the rotation rod is rotatingly connected to the experimental box body, and the bottom of the rotation rod is connected to a rotation base. A focusing handle is vertically arranged in the rotation rod and is at the bottom of the experimental box body. The focusing handle is connected to the half-wave plate through a fine adjustment tube. The rotation rod is internally and horizontally equipped with a limit plate. The focusing handle goes through the limit plate, and the side of the rotation rod is connected to a rotation block. According to the polarimeter, the all-round adjustment of an angle can be facilitated, at the same time the adjustment is flexible, the structure is simple, an experimental phenomena can be showed visually, thus students can accept the principle of the experimental phenomena well, the measurement precision is high, and an error is reduced greatly.

[0002] Polarimeters have been widely used in teaching experiments. With the rapid development of social economy, the whole society and the country attach great importance to education issues. Science and technology are the primary productive forces. Educational projects are urgently needed in all walks of life. During the entire education process All kinds of educational equipment are needed. In the entire educational structure, the state attaches great importance to the education of physics and mechanics, so the state also advocates that relevant technical personnel can create more and better physics teaching equipment. It is one of the professional measuring equipment of polarimeter to measure the optical rotation of the substance. By measuring the optical rotation of the sample, it can analyze and determine the concentration, content and purity of the substance. It is widely used in pharmaceuticals, drug inspections, sugar, food, spices, Monosodium glutamate and chemical, petroleum and other industrial production, scientific research and teaching departments are used for laboratory analysis or process quality control. However, most current polarimeters for physics teaching have certain defects in structural design, and the measurement accuracy of these polarimeters is low. , bulky and cumbersome to operate
