spot diameter on detector, or connectorized fiber with
NA 50.2
w
Ambient temperature 0 to 40°C, non-condensating.
w
Within 1 year after calibration, add 0.3% for the second year.
[3] Add O.OO7dBldB between 10 and 27dBm.
[4] 30° C for >2OdBm input power.
Supplementary Performance Characteristics
Add 1

to total uncertainty for the full wavelength range.
Outside the specified wavelength range, the noise increases by up to 5 times the
value shown above.
For fiber applications with NA between 0.2 and 0.3 use specific lenses and add
0.5% total uncertainty for the 85Of 5Onm, l3OOf 5Onm, and l55Of 5Onm range.
