www.roithner-laser.com 3 Precautions Static Electricity: VCSELs are sensitive to electrostatic discharge (ESD) . Precautions against ESD must be taken when handling or operating these VCSELs. Surge voltage or electrostatic discharge can result in complete failure of the device. Safety Advice: This VCSEL emits concentrated infrared light which can be hazardous to the human eye and skin . This diode is classi fied as CLASS 3B laser product according to IEC 60825- 1 and 21 CFR Part 1040.10 Safety Standards. Operation: Do only operate VCSELs with a current source. Running these LEDs from a voltage source will result in complete failure of the device. Current of a LED is an exponential function of the voltage across it. Usage of current regulated drive circuits is mandatory. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice Optical Output Power vs. Temperature Threshold Current vs. Temperature Spectral Emission FFP
