Ideally suited for simple, clear & easily comprehensive assemblies for interference &  diffraction experiments. The laser is constructed is such a way that is safe to use under any circumstances. Laser tubes along with in-built power supply are housed in thick powdered coated metal cabinet and produces  an intense beam of light at a wavelength of 632 nm. Design for continues working, highly rugged mechanical setup. Up-Down motion for beam. Provided with two stem rod of 10mm appro. which can be fix in laser base , can be held conveniently in a rigid mounts or for attaching it to various optical assemblies
