Гелій-неоновий лазер

Гелій-неоновий лазер
Monochromatic, coherent light source for optical experiments, e.g. on diffraction, interference, and hologram reconstitution. Anodised metal housing with key switch, neutral filter for attenuating beam, 2 stand rods and power supply unit. To widen the beam, microscope objectives (eg W30614) can be screwed to the beam aperture.
