Laser Pointer, Red

Economical laser pointers are useful for many optical experiments. Lasers operate on a push-button switch, are housed in a rubberized aluminum pen-style case, and include a pocket clip. The lasers are Class 3R, and are each 6╬ô├ç├Õ long x 0.5╬ô├ç├Õ diameter.

Red laser pointer has a maximum output of 5mW and a wavelength of 650nm (+/- 10nm). Range of beam is 100 meters. Expected operating life is 1000 hours. Operates on two "AAA" batteries (not included).
