Introduction


The LEOK-1 Optics Experiment Kit is designed for general physics education at the university and college level. It provides an economic and comprehensive solution for conducting a range of experiments in geometrical optics, physical optics, and information optics. The kit enables students to explore fundamental optical properties and principles, with hands-on experiments that develop practical skills in optical measurements and problem-solving.


The kit includes detailed instruction manuals with experimental setups, principles, step-by-step guidance, and photos of required components. These resources help students to easily grasp optical concepts and improve their experimental techniques.


The LEOK-1 Optics Experiment Kit allows students to conduct the following eight key experiments:

1. Measuring the focal length of a positive thin lens using auto-collimation method

2. Measuring the focal length of a positive thin lens using displacement method

3. Assembling a slide projector

4. Young’s double-slit interference

5. Fresnel diffraction of a single slit

6. Fresnel diffraction of a single circular aperture

7. Abbe imaging principle and optical spatial filtering

8. Pseudo-color encoding, theta modulation and color composition


The LEOK-1 Optics Experiment Kit is a cost-effective and versatile tool for teaching a broad spectrum of optical principles and phenomena. With eight carefully designed experiments, it provides students with a solid understanding of core concepts such as lens properties, interference, diffraction, and spatial filtering. The included instructional materials ensure that students can easily follow the experimental setups and gain valuable hands-on experience, enhancing their understanding of the fascinating world of optics.
