Figure 5 Noise Eaters Normalized Responsivity
5.2. Max Powers at Various Wavelengths
The tables below list the maximum input powers for each noise eater, specified for
a variety of input wavelengths and switch settings. Please note that these
maximum power levels correspond to the feedback electronics of the noise eater,
and in some cases, the actual maximum input power is instead limited by the
damage threshold of the noise eater. For the high power noise eaters (NEL02A,
NEL03A, and NEL04A), this damage threshold is 8 W/cm
2
, which corresponds to
a maximum input power of 1 W if the input power is distributed evenly across the
Ø4 mm clear aperture. For the low power noise eaters (NEL01A), the damage
threshold is 0.8 W/cm
2
, which corresponds to a maximum input power of 100 mW
if the input power is again distributed evenly across the Ø4 mm clear aperture.
