Power Meters FAQ's

Laser Power Meters



They are related, but not exactly the same. “Raw” is one of two options for setting the Analog Output. Basically, the Analog Output can be set by the user in 2 ways:

  • The source of the Analog Output is the processed (Digital) reading, in which case the Analog Output voltage represents the calibrated laser power (this is what is normally meant by “Analog Output”);
  • The source of the Analog Output is the unprocessed sensor input (Raw). In this case, the analog output voltage is a continuous non-digitized output. It is derived directly from the amplified sensor input signal, with little conditioning. The ‘Raw’ analog output option can be useful for analyzing the temporal shape of fast laser pulses.
