Note: (a) Depending on room airflow and temperature variations. Lowest measurable powers are achieved by thermally quiet room conditions, using removable snout (for 3A, 3A-P, 3A-PF-12 sensors), averaging and offset subtraction. (b) For P and PF types and shorter wavelengths derate maximum energy density as follows: P type PF type Wavelength Derate to value Derate to value 1064nm Not derated Not derated 532nm Not derated Not derated 355nm 40% of stated value 70% of stated value 266nm 5% of stated value 15% of stated value 193nm 10% of stated value 5% of stated value (c) Calibrated from 193nm to 2.2μm and at 10.6μm. There is an additional error of ±1% from 450nm to 650nm. (d) The 3A and 2A-BB-9 sensors have a relatively large spectral variation in absorption and has a calibrated spectral curve at all wavelengths in its spectral range to the above specified accuracy. Nova, Orion and LaserStar meters do not support this feature and when used with those meters, the accuracy will be ±3% as above for 532nm, 905nm, 1064nm and 10.6μm but there will be an additional error of up to 3% at other wavelengths in the spectral range 190 – 3000nm.
