Dual red and green laser pointer for optical experiments.

• Class 3R (Class IIIa) laser <5 mW
• Green wavelength of 532 nm (±10 nm)
• Red wavelength of 650 nm (±10 nm)
• Expected operating life is 1000 hours

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 L×D: 6×0.5".

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

Green laser pointer has a maximum output of 5 mW and a wavelength of 532 nm (±10nm). Range of beam is 200 meters. Expected operating life is 1000 hours. Operates on two 'AAA' batteries (not included).

Dual laser pointer (red/green) has a maximum output of 2×5 mW and a green wavelength of 532 nm (±10 nm) and red wavelength of 650 nm (±10 nm). 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).
