• [First choice for teaching]: very suitable for teachers, home schools and young scientists. It is an ideal choice for teachers, home schools and young scientists.
• [Covered content]: small hole imaging/light reflection/light refraction/lens imaging method/direct light/light three primary colors/concave-convex lens imaging method, etc. A scale is marked on the guide rail to facilitate observation and summary of the rules.
• [Optical bench kit]: scales are marked on the guide rail to facilitate viewing and summarizing the rules. It is not only a set of physics teaching experiment equipment, but also a gift for children's scientific exploration.
• [Scope of application]: various equipment packages for junior high school and high school physics laboratories.
• [Lightweight]: The length of the guide rail of this product is 96 cm, which is lighter than the traditional optical platform.
