Class 2 laser are safe for classroom use.

• Maximum output of less than 1 mW
• Push-button switch

These economical laser pointers are useful for many optical experiments. Their lower power output is ideal for middle school and high school classrooms. The lasers operate on a push-button switch, are housed in a rubberized aluminum pen-style case, and include a pocket clip.

The 6" long × 0.5" diameter Class 2 Red laser pointer has a maximum output of 1 mW and a wavelength of 650 nm (±10 nm). Range of beam is 75 meters. Operates on two 'AAA' batteries (included).

The 6" long × 0.5" diameter Class 2 Green laser pointer has a maximum output of 1 mW and a wavelength of 532 nm (±10 nm). Range of beam is 125 meters. Operates on two 'AAA' batteries (included).
