He-Ne Laser

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, handle and power supply unit. To widen the beam, microscope objectives (e.g. W30614) can be screwed to the beam aperture.
