Swing-Out Condenser, 1.3 n.a., Earlier Type
$80.00
This is an example of the earlier Zeiss swing-out condenser. The numerical aperture of the upper element is 1.30. When swung to the side, the condenser aperture is 0.32. There is an iris diaphragm for control of aperture. It has the standard Z-ring for mounting on the condenser carriers found on most of the ‘Gray-line’ Zeiss instruments.
While optically in great condition, the condenser has some cosmetic issues. Someone ground off opposite sides of the upper lens mount and the chrome plating has peeled from most of the bezel. The retaining ring for the clear glass plate above the iris diaphragm has some minor paint loss. There appears to be one leaf in the diaphragm that isn’t moving correctly, leaving a slight tear-drop shape to the aperture when it has been mostly closed (see photo of under side).
The oil-immersion 1.3 n.a. condensers are relatively scarce compared to the 0.90 type. This is a very serviceable item.
