ISO 9345-2:2003 Optics and optical instruments - Microscopes: Imaging distances related to mechanical reference planes - Part 2: Infinity-corrected optical systems
This part of ISO 9345 specifies the imaging distances of objectives, eyepieces and the focal length of "normal" tube lenses of microscopes with infinity-corrected optical systems.
NOTE A specific combination of eyepiece, objective and tube lens is frequently used to correct aberrations. Therefore the combination of an objective from one manufacturer and the tube lens or eyepiece from another manufacturer, although conforming to this part of ISO 9345, may cause errors in magnification and/or in optical performance.
