TW-PE-B Polarized Optical Rotation Tester Introduction: The polarimetric effect has many applications in scientific research and technical detection departments, such as the pharmaceutical industry, drug inspection and commodity inspection departments often use the polarimetric method to measure the concentration of drugs and commodities (such as cocaine, nicotine, camphor, etc.), and the polarimeter is also one of the instruments used to detect sugar content in the sugar industry and food industry. Compared with other polarimeters, this polarimeter has the following advantages: characteristic: 1. Students have a lot of hands and brains, and obvious physical phenomena, reflecting many advantages and characteristics of teaching instruments. 2. It can do a variety of polarized light experiments: optical rotation effect, optical polarization experiment, Marius law verification, etc. 3. Small size and light weight. High strength aluminum alloy is used to make light tool base, slider and turntable, which are beautiful and durable. This instrument can be used in basic physics experiments, design and research physics experiments and demonstration experiments. The following experiments can be completed with this instrument: 1. Used for polarized optical rotation experiment: 1) Understand the optical rotation characteristics of some substances and measure the optical rotation. 2) Measure the optical rotation of the optical rotator and the concentration of the optical rotator to be measured. 3) Confirm whether the optical active substance is right-handed or left-handed. 2. Used for optical polarization experiment 1) Understand and master the generation and inspection methods of circular and elliptical polarized light. 2) Verify Marius' Law. Technical parameters: 1. Semiconductor laser: wavelength 650nm, power 1.5-2mW, working voltage 3V. 2. Light fixture base: 650mm in length, 1mm in indexing value, and 5 sliding blocks. 3. Polarizer with turntable: 2, turntable scale 0 ° - 360 °, division value 1 °. 4. With photoelectric receiving power meter: range 200uW and 2mW, three and a half LCD display. 5. Sample tube adjusting bracket and sample tube: 1 sample tube with a length of 110mm.
