Ive been told Laser glow's lasers are measured and accurate when they ship, and I ordered a 3-5mw green and red from them so when they show up and the X4 shows up ill test them and report back.
Looking forward to it. I put up a graph from the X4 in a build thread for the Aixiz 8x31 module I mentioned in an earlier post. It shows a definite "stairstep" I assume is related to resolution, but provides repeatable results that "seem to match" the advertised power of the module.Ive been told Laser glow's lasers are measured and accurate when they ship, and I ordered a 3-5mw green and red from them so when they show up and the X4 shows up ill test them and report back.
Agreed -- it is difficult. The environmental influences like air movement, sunlight, skin radiation, etc. can be minimized by shielding the sensor (as you did with a box). But the distance from the sensor also makes a big difference in the reading, so I'm not sure exactly what distance results in an "accurate" reading.So I have been playing with my x4 for a hour or so now and all I can say is that to get an accurate reading at less than 5mw is very hard.
So I ended up finally getting accurate reading on my two laserglow's with the x4 heatsink and laser as close together as I could get them, less than an inch. I had this setup in a box to eliminate air movement. I powered the x4 off of a USB battery pack so there was no wires running out of the box.
Final result is my libra tested an average of 3.6mw and
peak 4.1mw and my anser tested 4.2 avg and 4.7 peak.
