The sapphire crystal light guide block for laser beauty equipment (IPL) is a sapphire crystal with high transparency and purity. The light guide block used for laser beauty equipment is a cuboid optical glass with all six sides of optical glass. Polishing, coating a cut-off filter film on one of the end surfaces, the transmitted light is totally reflected around the light guide block and finally emitted from the other end surface, and then irradiated to the skin surface for laser beauty.
