Frequently Asked Questions
Q: What material is this triangular prism made from, and why does it matter?
A: This prism is made from K9 optical crystal glass, which is a high-clarity borosilicate-type glass widely used in precision optical instruments. Its exceptional transparency and consistent refractive index ensure that light is dispersed cleanly and vividly into the full seven-color rainbow spectrum, making it far superior to basic plastic prisms for both science education and photography.
Q: Which size should I choose for classroom or home use?
A: All three sizes produce brilliant rainbow effects. The smallest (2.5×2.5×2.5 cm) is great for young children and portable experiments. The medium (2.5×2.5×3 cm) offers a good balance of size and brightness. The largest (2.5×2.5×5 cm) creates the widest, most dramatic color spread — ideal for classroom demonstrations or photography projects.
Q: Is this prism safe for children to use?
A: The prism is made of solid optical crystal glass and is designed for hands-on exploration by school-age children. As with all glass items, adult supervision is recommended for younger children. The smooth, polished edges minimize sharp points, and the compact size makes it easy for kids to hold and handle comfortably.
Q: What is the best way to get a clear rainbow effect with this prism?
A: For the best results, hold the prism up to direct natural sunlight — a sunny window, balcony, or outdoor setting works perfectly. Slowly rotate the prism at different angles until you see the full spectrum projected onto a nearby white surface such as a wall, paper, or floor. The clearer the light source, the more vivid the rainbow display.
