LCP-19 Measurement of Diffraction Intensity
This experimental system is suitable for general physics experiment teaching at universities and colleges. The key features include stable performance, easy operation and accurate reading. It helps students to understand the basic principles of Fraunhofer diffraction, and measure the intensity distribution of Fraunhofer diffraction. Through this system, students can enhance their hands-on experimental skills and analytical ability
