I read in a post somewhere that even a few mW's of IR can give a false reading on the meter(something about the sensor not being thermal?) and that you should place a high quality IR filter in the beam path that has a known transmittance at 532nm so wattage can be determined on some of the cheaper lasers.
If one were to just move all the lasers being tested a measured distance from the unit, say one meter distance, would that be enough to reduce the IR energy to a level where it's not a factor?
If an IR filter is the best option, anyone know of a good source?
Thanks.
