These are a pair of 16mm 5 element design with a field flattener lens from Carl Zeiss top of the line microscopes. By popular demand, I have incorporated the Baader planetarium T2 nosepiece adapter over the 30mm standard eyepiece barrels. The adapter is threaded for standard 1.25" filters and has captive setscrew grooves to secure the eyepieces. The eyepieces have a field stop of 16mm and high eye relief.
