Description

Laser experiments in reflection, refraction and diffraction are staples in physics. Holding the laser steady, and in the proper position, is important for experimental consistency. This apparatus that allows you to securely hold a laser pointer at any angle and the clip can hold the toggle button in the “on” position for extended demonstrations and experiments. The laser support rod is 8” long and has a vinyl coated clip to hold the laser pointer securely without scratching. The heavy cast iron base is 4” X 6” with black enamel finish. The 18 “ long zinc-plated steel rod has a diameter of 5/16”. The swivel clamp gives you the freedom to adjust the angle of the laser pointer360°. The clamp is plated steel and accepts rods up to ¾" diameter (19 mm). Length across clamps is 4.5". The red laser pointer operates on a push-button switch and are housed in a rubberized aluminum pen-style case. The laser is Class 3R and is 6” long x 0.5” diameter. Red laser pointer has a maximum output of 5mW and a wavelength of 650nm (+/- 10nm). Range of beam is 100 meters. Expected operating life is 1000 hours. Operates on two "AAA" batteries (which are included).
