I picked up some Unitron and old Criterion equipment, and it came with a cigar box full of components that look like they are from a focuser.
Three separate parts
One is a set of focuser looking components that have a built in lens on one end, and a threaded lens component on the other end. These pieces are also the only marked pieces - they have say - "XAW1"
One has a lens component only on oneend, and is open on the other side. The hole in the top of this piece is threaded, but is slightly smaller than a standard microscope eyepiece size.
The third component is a heavy screw type component, and also has a threaded lens on one end. It is much smaller - almost like .965.
Can anyone hele me identify these pieces?
