The PL-VCSEL-0850-0-A82-TO46 850nm VCSEL is a vertical emitting MOVPE grown GaAsP/AlGaAs Single Mode diode laser. The chips are mounted in TO46 can. Wavelength tuning can be achieved via laser current. package with TEC and PD Built in(Optional). It is special designed for FTIR Application. Good Narrow linewidth and low cost made it a great low cost choice for FTIR Application.

Safety and Operating Considerations
This device operates under reverse bias voltage, and the polarity of the device can’t be reversed.
Operating the Photodiode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power.
ESD PROTECTION—Electrostatic discharge (ESD) is the primary cause of unexpected laser diode failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling Photodiodes.
