Introduction
The LEOK-series Optics Experiment Kits are developed for general physics education at universities and colleges. LEOK-6 is an extension of LEOK-1 to include more experiments, especially optical polarization. It can be used to construct more than one dozen of experiments, covering the basic experiments in geometrical optics, physical optics, and information optics. LEOK-6 offers an affordable solution for covering a wide range of optical properties and principles. All experiments are performed along a rail and hence the system is suitable under normal lab environment. The instructional manual contains comprehensive materials including experimental configurations, principles, procedures and required parts with photos. Please click to view some sample pages of the instruction manual. Through self-selecting individual components and self-constructing complete setups, students can enhance their experimental skills and problem solving ability.
