About This Product
Compared with a broad light source, the narrow beam makes straight-line propagation, mirror reflection and refraction through prisms and lenses easy to trace and compare with ray diagrams. With slits or gratings it also shows diffraction and interference, and it doubles as an alignment aid on an optical bench. Educational Instrument can arrange export supply of the Red Diode Laser to Indonesia, Bahamas, Paraguay, Venezuela and Mauritania.
