Description
UVMAX270 is a series of AlGaN based deep UV multi chip LED arrays, typically utilizing 4-5 parallel strings (common cathode),
each carrying up to 18 (9x2) pcs of chip dies in combined serial and parallel connection. UVMAX270 features total optical output
power of 30-50 mW at a nominal current draw of 900mA, and typical emission wavelength of 275 nm. It comes in hermetically
sealed TO3 metal can package with hemispherical SiO2 lens or flat SiO2 glass window configuration, and integrated thermistor.
UVMAX270 is widely used for forensic analysis, disinfection, water sterilization, protein analysis, DNA sequencing and drug
discovery. UVMAX270 can optionally be equipped with an integrated thermo electric cooler.
