Samarium Foil (Light Tight) is a thin metallic foil that blocks light transmission and comes in 3 thicknesses, ranging from 25 to 100 microns. With a silvery-white luster, samarium foil exhibits typical metallic properties like ductility and electrical conductivity. Due to its opacity to light, it can be used as a radiation shield in scientific instruments and as a light barrier in certain electronic components, as well as many other light blocking applications. This feature also allows it to be incorporated into optical filters and spectrometers for selective wavelength blocking.
