Materials Prism glasses made from optical glass. The glass part can be removed for singleuse applications. Applications Essential equipment for nature science study in kindergarten and primary school, and for light dispersion and refractor research in school. Suitable for teaching the physics of the light spectrum. Benefits and features Ideal as a classroom teaching tool or as an intellectual development toy for children. Provides an initial experience of light refraction, helping to stimulate curiosity and exploration. Accessory Includes a sturdy plastic holder stand, convenient for changing the prism angle. Use scenarios 1) Kindergarten and primary school: use to demonstrate basic dispersion of light and color separation in a simple, handson way. 2) school physics: use in lessons and experiments to study light dispersion, refraction, and spectrum analysis. 3) Classroom or home learning: serve as a reliable demonstration tool to engage students in practical exploration of light perception and optical concepts.
