ABSTRACT:
The invention is directed to objectives for imaging small regions with a large aperture angle. The objectives include two aspheric bodies made of optically isotropic material wherein the deflection of the light rays is achieved by total reflection on the outer surfaces. The light entry surfaces and light exit surfaces are configured as spherical surfaces having center points at least approximately coincident with the focal points of the aspheric bodies.
