ABSTRACT:
An objective lens for microscopes has an optical unit removably disposed at the front end of the objective lens. The optical unit includes at least two kinds of optical elements having different optical properties. Thus, the objective lens for microscopes can always maintain good imaging performance in the case where either a glass or plastic vessel is used.
