Описание (английский):

This document specifies optically and mechanically related dimensions for imaging components of a microscope such as a) the dimensions related to objective, eyepiece and tube lens, b) the dimensions of screw thread types for connecting a microscope objective to the nosepiece, and c) the diameters of interchangeable eyepieces and corresponding viewing tubes of microscopes.

Overview - ISO 9345:2019 (Microscopes: interfacing dimensions for imaging components)

ISO 9345:2019 defines the opto-mechanical interfacing dimensions for microscope imaging components. It standardizes nominal dimensions and tolerances for key parts such as objectives, eyepieces, tube lenses, connecting screw threads (objective ↔ nosepiece), and interchangeable eyepiece/viewing-tube diameters. The document includes tables, figures and informative annexes with examples for infinity-corrected systems, cover-glass parfocal adjustments, and OEM recommendations.

Key topics and technical requirements

Imaging distances and reference planes: parfocalizing distances for objectives and eyepieces (e.g., common objective parfocalizing distance l1 = 45 mm for 160 mm tube length; eyepiece parfocalizing distance l3 = 10 ± 0.2 mm); mechanical tube length l4 = 160 ± 0.5 mm where applicable.

Objective-to-primary-image and tube-lens parameters: objective primary image distance (finite values like 150 mm or infinity for infinity-corrected systems); focal length range for a normal tube lens fNTL between 150 mm and 250 mm.

Thread standards for objectives/nosepieces: recommended screw thread types and dimensional tolerances for RMS, W26 and metric threads M25, M27, M32, with detailed limits of size, pitch and play to ensure mechanical compatibility.

Eyepiece and viewing-tube diameters: nominal diameters such as 23.2 mm or 30.0 mm (with specified tolerances) to support interchangeable eyepieces.

Marking and tube factors: requirement to mark tube magnification changes (e.g., “1.25×”) when built-in optics alter primary image magnification.

Informative annexes: Annex A (examples for infinity-corrected systems), Annex B (parfocal distance vs cover-glass thickness), Annex C (OEM recommendations).

Practical applications - who uses ISO 9345:2019

Microscope manufacturers (OEMs) designing optical trains and nosepieces to ensure component interchangeability.

Objective/eyepiece and tube-lens suppliers to produce parts that fit common microscope platforms.

Laboratory instrument engineers and designers integrating microscope modules into imaging systems.

Quality, procurement and calibration teams verifying dimensional compliance and mechanical compatibility.

Repair and maintenance services replacing objectives, eyepieces or nosepieces while preserving optical alignment.

Related standards

ISO 10934-1 (microscopy vocabulary) is normatively referenced for terms and definitions.

ISO 9345:2019 supersedes earlier documents such as ISO 8038:2013, ISO 9345-1:2012, ISO 9345-2:2014 and ISO 10937:2000.

Using ISO 9345:2019 helps ensure mechanical interchangeability and predictable optical performance across microscope components-key for reliable imaging systems, component sourcing, and OEM system integration.
