ams OSRAM LZ4 LuxiGen™ UV LED Emitters are 365nm high flux density LEDs with an integrated flat glass lens. These LED emitters are available in a surface-mount ceramic package and offer 1.1°C/W low thermal resistance. The ams OSRAM LZ4 LED emitters have a 2.2mm x 2.2mm Light Emitting Surface (LES) in a 7mm x 7mm emitter footprint. These LED emitters are ideal for imaging optics with beam angles as narrow as ±3°. The LZ4 LED emitters come in two variants: the LZ4-04UV0R-0000 UV emitter and the LZ4-V4UV0R-0000 UV emitter on a 4-channel Cu star MCPCB. Typical applications include curing, printing, PCB exposure, sterilization, medical, currency verification, fluorescence microscopy, inspection of dyes, rodent and animal contamination, and forensics.
