Epiplan HD 6.3 / 0.16 Microscope Objective
$180.00
Here is a wonderful condition Zeiss incident light objective with darkfield illumination capability (HD, for Hellfeld / Dunkelfeld). This objective is quite scarce – the magnification (6.3 times) places it in the early series of the Epiplan HD lenses which included 6.3, 10, and 25, not found in the far more prevalent later series. Numerical aperture of this lens is 0.16.
The thread diameter of the objective is 24 mm (the Zeiss “HD” thread), and the adjustment length of the lens is 33 mm (distance from the specimen to the thread seat when properly focused). This objective is therefore parfocal with the later Epiplan HD series. The lens is also corrected for flat field. The outer mirror bezel can be adjusted by loosening the lower set screw . This allows the user to carefully set the optimum illumination for the sample being observed. For most applications, the bezel can be left in the original factory set position. I am not certain about working distance of this particular lens – the objective is recessed quite a ways beneath the level of the reflector, however, and is therefore relatively well protected.
Condition of the objective is superb – no damage to the front lens, and no delamination anywhere. Even the chrome bezel is cosmetically close to perfect. Serial number of the lens is 4056408.
