- Scope
- This part of GB/T 22055 specifies the dimensions of the M25-type thread that is different from the RMS standard for connecting the microscope objective lens and the nosepiece. NOTE: A specific system of eyepiece, objective, and tube lens (for example, an infinity-corrected optical system) is usually aberration-corrected, so an objective made by one manufacturer and a tube lens or eyepiece made by another Combinations, even if they all comply with the provisions of this section, may still cause errors in magnification and/or reduction in image quality.
