OBJECT LENS HAVING CONIC SECTION SHAPED REFLECTING SURFACE

For imaging small regions having a large aperture angle, objectives are specified which consist of two conical section elements (e.g. 1a, 1b, 6a, 6b) made of optically isotropic material, and in which the deflection of the light beams is performed by total reflection at the generated surfaces (e.g....

Beschreibung
Zusammenfassung:	For imaging small regions having a large aperture angle, objectives are specified which consist of two conical section elements (e.g. 1a, 1b, 6a, 6b) made of optically isotropic material, and in which the deflection of the light beams is performed by total reflection at the generated surfaces (e.g. 10, 15, 60, 65). The light entry and exit surfaces are constructed as spherical surfaces (e.g. 13, 18, 63, 68) whose midpoints (e.g. 14, 19, 64, 69) are united at least approximately in one point with the focal points (e.g. 11, 16, 61, 66) of the conical section elements.
