Photo eyepieces and eyepiece adapter tubes
Not for visual observation, only for adaptation of
Leica DM LD and MPS photomicro systems,
mounting diameter 27 mm, together with special
eyepiece adapter tube (36.4).

Eyepiece field of view number
For certain microscope configuration certain
eyepiece field view number must not be
exceeded (see below), e. g. 20. If the maximum
field of view is exceeded, there may be a
disturbing loss of definition or vignetting at the
edge of the image, see following pages!
The eyepiece field of view (fov) stands for the
diameter of the intermediate image in the
eyepiece in mm, i. e. the diameter of the circular
diaphragm which defines the image format and
which lies roughly in the center of the eyepiece.
This fov is indicated on the eyepiece after the
magnification, e. g. 10x/20.

The maximum admissible eyepiece field of view
number of certain configuration is derived from
the following instrument data:
Field performance of objectives
Field performance of intermed. module(s) → p. 25
Field performance of tube
Illumination of condenser
The decisive value is always the smallest. If, for
example, the intermediate modules (see below)
only allow the field of view number 20, but the
objectives and tube 25, the maximum field of
view number for the eyepieces is 20. Eyepieces
with the field of view number 25 can lead to
vignetting. In detail, the following applies:
Field performance of objectives
The engraving on the objectives does not
include their field performance. It can vary
slightly within a class of objective, e.g. the lower
objective magnifications may well have higher
values than the approximate values given
below:
