Introduction

With the rapid development of optoelectronic technology in the early 21st century, the application of optical thin film devices has developed rapidly with higher performance in wider application fields. In order to enable students to adapt to development, expand the scope of knowledge, broaden their horizons and improve their abilities, a comprehensive optical thin film measurement experiment was developed to conduct research on commonly used coated sheets on the market. From the principles of coating to the testing of actual samples, students can understand the principles and applications of optical coatings thoroughly.
