Periplan GF 10x M Single Microscope Ocular
$110.00
This is a single Leitz Periplan GF 10x eyepiece with a focusable eyelens. It is for use in the standard DIN size ocular tube (23.2mm diameter). The diaphragm is located 18mm beneath the end of the flange so it is suitable only for the earlier Leitz instruments with a 170mm mechanical tubelength (Orthoplan / Ortholux 2 era and earlier). It may be used in the later and current stands if an 8mm adapter collar is installed (not included).
The Periplan designation means that the optics have a more highly corrected eyelens. The GF denotes Gross Field, but with a field-of-view index of 18mm it is not as large as the GW series which have a 30mm diameter ocular sleeve. This eyepiece has a focusable eyelens and comes with a threaded reticle retainer ring (reticle diameter is 17.5mm). No reticle is included.
This may be paired either with another focusable ocular, or with a fixed eyelens ocular. It should be noted that Leitz made at least three different height GF 10x oculars (the height of the upper bezel to the sleeve flange). The earliest GF oculars were only about 3mm proud of the ocular tube. The next series were 9mm tall. This ocular (when set to the nominal focus plane indicated by a radial groove) is about 14.5mm tall, which means it is one of the last in the series. When selecting a second Periplan GF 10x eyepiece, make sure to determine that the height is similar – although the magnifications and the field of view of all the oculars are identical, it is very disconcerting to have one eyepiece further away than the other!
The lens is in near mint condition, and the optics are completely free of blemishes.
