Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9345-1 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 5,
Microscopes and endoscopes.
This second edition cancels and replaces the first edition (ISO 9345-1:1996) which has undergone a minor
revision to align definitions with ISO 10934-1 and to adjust presentation to ISO 9345-2.
ISO 9345 consists of the following parts, under the general title Microscopes — Imaging distances related to
mechanical reference planes:
— Part 1: Tube length 160 mm
— Part 2: Infinity-corrected optical systems

INTERNATIONAL STANDARD ISO 9345-1:2012(E)
Microscopes — Imaging distances related to mechanical
reference planes —
Part 1:
Tube length 160 mm
1 Scope
This part of ISO 9345 specifies the imaging distances of objectives and eyepieces of microscopes with 160 mm
mechanical tube length or equivalent.
NOTE A specific combination of eyepiece and objective is frequently used to correct aberrations. Therefore, the
combination of an objective from one manufacturer and an eyepiece from another manufacturer, although conforming to
this International Standard, might cause loss of image quality.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
parfocalizing distance of the objective
distance in air between the object plane (i.e. the uncovered surface of the object) and the locating flange of the
objective, when the microscope is in its working position
Note 1 to entry: The parfocalizing distance of the objective is one of the optical interfacing dimensions.
[ISO 10934-1:2002, definition 2.80.2.4]
2.2
objective to primary image distance
distance in air between the objective locating surface (of the nosepiece) and the primary image plane
Note 1 to entry: The objective to primary image distance is one of the optical interfacing dimensions and commonly
has a value of either 150 mm or infinity. The latter is a hypothetical value applied to microscopes designed for infinity-
corrected objectives.
[ISO 10934-1:2002, definition 2.80.2.1]
2.3
parfocalizing distance of the eyepiece
distance between the locating flange of the eyepiece and
