This system enables you to quantitatively investigate diffraction effects. To capture and analyze the diffraction patterns, we use a photocell to transform the diffraction pattern into current which is displayed by LED.
As it is designed for students to improve and consolidate their understanding on intensity distribution of diffraction, this system allows students to draw curves of the diffraction pattern with numerical data recorded. Student may get a better idea of the wave nature of light and an improvement in the ability to analyze and DIY skills.
