What is aberration?
The following is an explanation of aberration, which is a distortion from the ideal image of a microscope.
Coverglass and correction ring
This is an explanation of the standard for the coverglass used in microscopes, and of the spherical aberration that occurs in the coverglass. Also, the function of the correction ring that is contained on some objective is explained.
Shear amount in differential interference
This is an explanation of the shear amount, which has an effect on the resolution performance in DIC observations.
