helium-neon laser

The Helium-Neon Laser (He-Ne Laser) is a monochromatic, coherent light source for optical experiments, e.g. on diffraction, interference, and hologram reconstitution, and can be combined with a microscope objective for diverging the beam.

benefits of the helium-neon laser

The Helium-Neon Laser is a high quality product suitable for a range of optical experiments and demonstrations. It comes in an anodised metal housing with a key switch, neutral filter for attenuating beam, two stand rods and a power supply unit. The beam can be widened by attaching the Achromatic Objective to the beam aperture, as shown in the second picture.
