Scope

This part of GB/T 22055 specifies the dimensions of the M25 thread connecting the microscope and nosepiece that are different from the RMS standard. NOTE: A specific system of eyepieces, objectives, and tube lenses (e.g., infinity-corrected optics) is often poorly calibrated, so a combination of an objective made by one manufacturer and an eyepiece made by another manufacturer, even if both comply with this specification. Some regulations may still cause errors in magnification and/or degradation of image quality.
