Leitz NPL 5x / 0.09 Metallurgical Microscope Objective
$180.00
This Leitz microscope objective was intended for the examination of metallurgical or semiconductor samples..It is corrected for a flat field of view when using standard GF (GrosFeld) oculars, hence the Normal PLan or NPL engraving. PL objectives were intended to be flat over the entire 28 mm field of view of the super-wide-field Orthoplan and large metallographs – the NPL’s are most suited for the 18 mm to 20mm field of view.
Magnification � 5x
Numerical aperture � 0.09
Achromatic color correction
Flat field for normal 18mm oculars
Standard RMS thread
Adherance to zero coverslip not manditory
Adjustment length � 45mm
Working distance � 6.2mm (?)
Infinity corrected
The objective is infinity corrected as can be told by the ‘X’ mark following the magnification. While it is intended for samples without cover glass, the numerical aperture is small enough that it could be used in transmitted light with covered samples. It would still need to be employed in conjunction with an infinity corrected system, however. Attempting to use this optic with a 170 or 160 mm tube length system would introduce all manners of aberrations!
The lens is in superb condition – no scratches and the coatings are very strong. The lens dates from the early 1980’s since it rhas the relatively coarse knurl next to the thread seat.
Photo set 1962
