Laser Prism Set

Study refraction and reflection using the laser ray box and 7 prisms in this economical set. Laser light is bright enough to see even in a well-lighted room, so there is no need to darken your classroom while students work.
The ray box plugs directly into an AC outlet and is ready to use immediately.
Use the graduated circle printed on the set's mat to measure angles of reflection and refraction.
Mat is magnetic, perfect for working on metal desks, tables, or boards.
