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.

Note: (c)
Calibrated from 193nm to 2.2µm
and at 10.6µm. There is an
additional error of +/-1% from
450nm to 650nm.
Note: (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.
