I was curious about any IR leakage in my greenies, so I shined them through a diffraction grating and viewed the pattern through a night vision camera.
I didn't see anything unusual with my lower powered greenies, an 80mW CNI PGL III-A and a Nova X150.
However, I did see additional dots with my RPL and brand new PL-D, both of which are supposed to possess IR filters.
Boosted240 also recently measured his new PL-D 500 for IR leakage by placing goggles in front of an LPM and got 82mW.
Assuming these higher powered greenies use 2.5W IR diodes and IR filters that leak 2-3%, are these IR leakage results expected? :thinking:
