Yes. They have a small hole in one end that the optics "sees" out of.
They have about a 4:1 range to spot ratio, so if you hold it 12"
away from an object it "looks" at a 3" diameter spot.
Very handy for measuring lots of stuff....
It's nice to see they are made by Raytek. Raytek is one
of the 2 "biggies" in infrared thermography.
