He-Ne Laser (Random/Unpolarised) Red
Ideally suited for simple, clear & easily comprehensive assemblies for interference, diffraction and holography experiments. The laser is constructed is such a way that is safe to use under any
circumstances. Laser tubes along with SMPS power supply are housed in thick powdered coated aluminium Box. From the hole, the laser beam comes out.
