Handling Precauti***
These devices are sensitive to ESD. When handling the module, grounded work area and wrist strap must be used. Always store in an antistatic container with all leads shorted together.
How To Order
Part number example: PH1064DBR080BF. Assign optical power from those shown below. Use a three-digit format for all power entries. Call factory for special performance selection and certification to certain atomic absorption lines. Butterfly package is offered at 50% of output powers shown, and is not recommended for spectroscopy applicati***. See Photodigm’s application note titled “Optical Feedback”
