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
P type
Wavelength Derate to value
1064nm Not derated
532nm Not derated
355nm 40% of stated value
266nm 5% of stated valuee
193nm 10% of stated value
PF type
Wavelength Derate to value
1064nm Not derated
532nm Not derated
355nm 70% of stated value
266nm 15% of stated value
193nm 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. |
