Optical Probe Clarity

  1. May 4, 2016 #1
    I work in a lab that uses laser probes to test for vibration and other data, currently the lab techs hook up the probe to a laser source and check to see how bright and clear the beam spot is. I have been working on having a signal power budget created for each probe using a laser source and detector and calculating the probes power loss in dBm and dB.

    Am I wrong in believing this is a better option then just looking at the beam spot?

    What is the safety class of the laser?
