Optical radiation with wavelengths shorter than 400 nm λp is called ultraviolet (UV) radiation and is further subdivided in UV-A (320-400nm λp), UV-B (280-320 nm λp) and UV-C (180-280 nm λp) categories. These LED die are made from AlInGaN heavily doped with Aluminum MOCVD epitaxial wafers fabricated into dice that emit short wavelength UV radiation. It is this solid-state optical power that is being found to be highly compatible with a wide-range of applications. Standard devices are tested and sold to peak wavelength radiometric optical power measurements.UV devices range from 265 nm λp (265 nm λD) to 420 nm λp (434 nm λD). MARUBENI Tech-LED standard UV-C 265, 275nm UV-B 280, 310, 340nm, UV-A and Near UV 405, 415, 418, and 420 nm λp wavelengths are available as standard products. For these MARUBENI Tech-LED seeks your inquiry and will respond to your interests on a case by case basis. Standard products include epitaxial wafers, fabricated Known-Good Die (KGD™), and packaged devices including micro-miniature SMDs, standard lamps, COB/DOB compact micro-arrays (CMA™), modules and other UV sources including flashlights for portable lighting applications.
