Additional information
The resolution that can be achieved in optical microscopy is ultimately determined by the convergence angle of the objective lens. In refracting objectives this angle is limited, in theory, to 90 degrees. The use of an elliptical reflecting objective permits angles greater than 90 degrees to be achieved. Ellipses possess two foci and this paper presents the first rigorous vectorial theory describing the focusing of a dipolar electric field from one focus to the other. The analysis considers the high numerical aperture situation, corresponding to the use of such mirrors in high resolution imaging systems.
