BS ISO 9345-1:2012 PDF

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.
