ABSTRACT:
An optical system for microscopes to enable microscopes having objectives of infinite exit vertex focal length to be made compatible with microscopes having objectives of finite exit vertex focal length, and vice versa, thus enablying the microscope user having a microscope of one kind to continue to use his supply of interchangeable objectives if he acquires a microscope of the other kind, and enabling microscope manufacturers to stock only one style of objective even if both styles of microscopes are being manufactured or if a transition is being made from one style to the other. The invention provides adapters having optical elements which enable an objective of the finite exit vertex focal length kind to be used with a microscope designed for an objective of the infinite exit vertex focal length kind, or vice versa, the optical system of the adapter providing adequate compensation or correction for aberrations.
