For 0.5THz and below add 5% to error Note: (d) Back reflections from meter can sometimes cause interference effects with source. Unit should be tilted ~10o in this case. Note: (e) For P type and shorter wavelengths derate maximum energy density as follows: Wavelength Derate to value 1064nm Not derated 532nm Not derated 355nm 40% of stated value 266nm 10% of stated value 193nm 10% of stated value
