| Not a clue what this was made for. Assembly has a coated optical window on one end 9mm clear diameter. On the other end in the center is a 4mm diameter single element lens with a 3mm focal length surrounded by a coated optical window 7mm diameter. The optical assembly threads into a housing that is 30mm diameter with a 8mm diameter opening. Looks like that's designed to be some sort of a focusing mechanism as there is a knurled ring that is used to hold the optical assembly in place. Clearly an expensive piece and quite a bargain at our price if you can figure out a use for it. |
