To drive the LED we recommend using:
• LED drivers and evaluation boards
designed by LED Microsensor NT
• LED basic circuit connection
Pulse
Generator
LED
1 Ohm
We recommend to use Quasi Continuous Wave (qCW) mode with duty cycle 50% or 25% to obtain maximum average optical power and short Pulse
modes to obtain maximum peak power. Hard CW (continius wave) mode is NOT recommended.

IMPORTANT CAUTIONS:
●
●
●
●
●
check your connection circuit before turning on the LED;
mind the LED polarity: LED anode is marked with a RED dot;
do not connect the LED to the multimeter;
do not touch the glass covering and do not apply any force to it;
observe the allowable operating temperature range, exceeding this eange may cause irreparable damage of the glass cover
