About This Product
Laser pointers give a narrow beam that makes ray paths easy to see. In optics lessons they are used to show reflection from mirrors and refraction through blocks, to trace light along a path and to discuss wavelength, because red light of 670 nm has a single colour. This pointer is low power, with a maximum output below 1 mW, but a laser beam must never be pointed at eyes or at reflective surfaces. Use it under teacher supervision.
