Incident-light dark field objective for a microscope and method for adapting such an objective to a microscope

摘要

An incident-light dark field objective for use in an objective turret of a microscope, in which the front edge of the outer part of a dark field channel surrounding a front lens of the objective is bevelled, so that the objective turret may be pivoted without the front surface of the objective contacting the microscope stage or a stage insert therein. The invention also provides a method of adapting an objective to a microscope using a polishing device which corresponds in structure and dimensions to the micro- scope. The objective is mounted on the part of this device which corresponds to the objective turret and a polishing surface is arranged in the vicinity of the plane corresponding to the specimen plane of the microscope, the front surface of the objective being appropriately polished on the polishing surface.
