visible and infrared

EPIGAP Optoelektronik GmbH has developed for high-end optical applications new pointsource light emitting diodes that emit at 595, 645 and 850 nm. The point-source LED is a suitable light source for a photo sensor because it has a small emission area. It is composed of AlInGaP or AlGaAs material, features round emitting surface and has special design to provide high intensity of visible or infrared light within a small emission area. AlInGaP is more reliable in humid conditions in comparison with traditional AlGaAs LEDs. The devices are available in either chip form or mounted in a package. They can also be mounted on printed circuit boards or other substrates. Applications include medical (activation of photosensitive drugs), scanning systems, adjustment of optical devices.
