Not a lot to say here. But the topic of knowing if your reticle is lined up with the IR beam and or testing the Beam Size comes up often.
Simply knowing the spec'd beam size, draw or use a grid that represents the expected beam size at your test distance. I usually just use about 25 yards. Expect the reticle to be slightly offset when used so closely. Same issue as scope over bore.
Using NV, simply look at the IR light.. Here you can see that I marked expected 1.2x.5mil beam in black.. The blinking light is the Lecia 2700B in scan mode.
Most PLRFs are NV visible -- a few specific ones are not. Normally the PLRF's beam is brighter looking, but I had a lot of other IR stuff going on (long story) really bleaching the image. Image from my PCP pest control device.
Edited to add: if you don’t have NV you can use $39 WiFi with IR security camera found on Amazon with the free app. Plus you can use it for other things.
