United Scientific Dual Color Laser Pointer

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” long x 0.5” diameter.
• Dual laser pointer (Red/Green) has a maximum output of 2 X 5mW and a green wavelength of 532nm (+/- 10nm) and red wavelength of 650nm (+/- 10nm).
• Range of green beam is 200 meters.
• Range of red beam is 100 meters.
• Expected operating life is 1000 hours.
• Operates on two "AAA" batteries (not included).
