Ruggedly constructed lasers with hard-seal tubes for long life. Each is housed in a transparent blue, impact-resistant acrylic housing with positive grip rubber feet. The output end incorporates a manual beam-blocking safety shutter, and has a threaded mount for standard beam-shaping accessories. The rear panel carries the power switch and jack for connecting the included power adapter (UL approved, for 115V AC). A standard 1/4-20 threaded hole in the base accepts a stand rod for optical bench or tripod mounting (not included on 5.0mW model). The lasers emit red light with a wavelength of 632.8nm in the TEM00 mode. Includes full color instruction manual.Continuous Wave (CW) Lasers emit a continuous beam of light with only small output power variations after warm-up. They are suitable for most applications.Modulated Lasers have additional jacks (3.5mm audio) to allow a varying signal of 600Hz–20kHz to be input for modulating the output beam intensity. This is used for measuring the speed of light and for optical signal transmission experiments.An economical low power laser for laboratory work or classroom demonstrations.
Helium-Neon Lasers, Continuous Wave Laser, Class: II, Power: 0.5 mW, Case Size: 14-1/2 x 3-3/4 x 2-1/4"
