This weekend I finally purchased an LPM (the Hyperion Argentum to be specific).
I feel like this is pretty much a noob question, but I wasn't able to find what I was looking for as there was little documentation on this meter, other than the thread from astralist in 2016.
My question is, is there a standard distance from the sensor for all measurements? A recent post Review of the LaserBee AX Laser Power Meter (LPM) says that “For consistent readings, make sure that all measurements are taken at the same distance between the sensor and the laser being tested. (3" {7.60cm} to 1' {30.50cm}) and that the entire laser beam falls on the sensor..” Does the same standard go for all Laser Power Meters?
The reason I’m asking this is because while testing, for example, the NUBM07 with a G-8 Lens (at about 6” from the sensor, and the projected “bar” being the same size of the the sensor “not pinpointed”, the sensor began to produce smoke. This was just after maybe 10 seconds with the the display measuring around 2000mw. I was cooling the rear part of the heatsink with a small 40mm fan in-between readings, to prevent overheating. However I didn’t want to continue pushing it or even progress up to anything more powerful, before I knew if this is normal.
