Infrared, UV, Visible Emitters are semiconductor devices that produce light in the infrared, visible and ultraviolet frequency ranges (255 ~ 1720 nanometers). Often found in devices such as remote controls, optical wireless links, or alternative illumination sources, they can produce intense sources of radiation that more common light sources are unable to. With a range of electrical specification, case sizes and viewing angles, these items are able to fill a wide application role.
