PM200
W (nW, µW, mW)
A (nA, µA, mA)
dBm (1mW = 0 dBm)
Thermal sensors - they deliver a voltage proportional to the incident power:
W (nW, µW, mW)
V (mV)
dBm (1mW = 0 dBm)
Pyroelectric sensors - they deliver a voltage peak, proportional to the incident
pulse energy:
J (mJ)
V (mV)
Power / Energy Density
The calculation is based on the beam parameters, entered in Measurement
