I'm looking for a infrared viewer to see the infrared "footprint" of a photoeye's beam. I used one of these about 20 years ago, but I've forgotten who made it.
For those that haven't used one, it's the bomb for aligning photoeyes and reflectors. Just have someone stand behind the reflector with a sheet of cardboard and simply look through the viewer.
The infrared beam will show up as a circle on the cardboard. Then you simply align your photoeye so that the beam covers the reflector.
Swap places with your helper, and then adjust the reflector so that the return beam hits the photoeye.
Does anyone here use one?, and can anyone recommend one?
And finally, can I do the same thing with a nightvision scope?
Thanks.
