.5 -.33 μm To drive the LED we recommend the following basic circuit connections: LED basic circuit connection LED with thermoelectric module basic circuit connection Pulse generator LED Ohm thermocooler I adjust Constant current source We recommend using Quasi Continuous Wave (qcw) mode with a duty cycle 5% or 5% to obtain maximum average optical power and short Pulse modes to obtain maximum peak power. Quasi Continuous Wave (qcw) mode Pulse mode - μs Drive current f =.5 - khz 3- μs 3- μs max.. A Drive current f =.5 - khz - μs max. A Time Time IMPORTANT CAUTIONS: please check your connection circuit before turning on the LED; please mind the LED polarity: anode is marked with a RED dot; REVERSE voltage applying is FORBIDDEN; please do not connect the LED to the multimeter; please control the CURRENT applied to the LED in order NOT to EXCEED the maximum allowable values.
