Laser Pointers
Ideal classroom Instruments for all optical work 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 to 20 threaded hole in the base accepts a stand rod for optical bench or tripod mounting (not included on 5.0 mW model). The lasers emit red light with a wavelength of 632.8 nm 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 (3.5 mm audio) to allow a varying signal of 600 to 20 kHz to be input for modulating the output beam intensity. This is used for measuring the speed of light and for optical signal transmission experiments.Has higher power output to allow for holography or experiments requiring optical alignment.
