[0002] Optics is an important branch of physics. At present, optical knowledge has been introduced in primary school science subjects. However, simply explaining optical knowledge verbally is too abstract, boring and dull for students. Optics is also the focus and difficulty in teaching. Students should understand the characteristics of light propagation more intuitively. Color is closely related to our daily life, such as digital products, clothing and lighting, and it is also widely used in industrial production. Chromatology is a discipline that studies color measurement and evaluation methods. Therefore, it is very necessary to incorporate colorimetry related experiments into the physical experiment system and impart colorimetry knowledge to students.

[0003] Although some domestic universities have opened colorimetry experiments, most of them are mainly used to demonstrate the synthesis of three primary colors. There is a lack of quantitative colorimetry parameter measurement and design calculation.

It is not convenient to display the spectrum according to different convex mirrors or concave mirrors. The optical experimental effect is relatively general and there are fewer experimental options. For this reason, we propose an optical experimental device to solve the above problems. Utility Model Content
