Mirrors, lenses, and prisms reflect, refract, and split light into different colors. Available in different sizes, our high quality Plastic Mirrors are durable and just right for mirror writing, periscopes, and many other experiments. The Mirage uses mirrored surfaces to create a 3-dimensional real image. The Concave/Convex Mirror is double sided and curved and so has both a concave side and a convex side on a single mirror. Equilateral & Right Angle Prisms are made of optical glass or clear colorless acrylic plastic.
