CA 2401328

The invention concerns an aberration correcting optical relay (1) for an optical system. Said relay comprises two front and rear convergent optical blocks (2; 3) and a correcting meniscal lens or two correcting meniscal lenses symmetrically positioned relative to each other, the correcting meniscal lens or lenses having substantially concentric main surfaces (4), preferably exactly concentric, the two convergent blocks (2; 3) being positioned on a common axis and the correcting meniscal lens or lenses (4) on said axis and between the two convergent optical blocks (2; 3) the front convergent optical block (2) located upstream of the meniscal lens or lenses is arranged such that the distance between an image point of the part of the optical system upstream of the optical relay, and the front convergent optical block (2) is equal to the focal length of the front convergent optical block (2), the latter thereby transforming a beam derived from said image point into a parallel beam.

Relais optique correcteur d'aberrations (1) pour système optique. Ce relais comporte deux blocs optiques convergents avant et arrière (2; 3) et un ménisque correcteur ou deux ménisques correcteurs placés symétriquement l'un par rapport à l'autre, le ou les ménisques étant à faces principales sensiblement concentriques (4), de préférence exactement concentriques, les deux blocs optiques convergents (2; 3) étant placés sur un même axe et le ou les ménisques correcteur (4) sur cet axe et entre les deux blocs optiques convergents (2; 3). Le bloc optique convergent avant (2) situé en amont du ou des ménisques correcteurs (4) est disposé de manière à ce que la distance entre un point image de la partie du système optique en amont du relais optique, d'une part, et le bloc optique convergent avant (2), d'autre part soit égale à la focale du bloc optique convergent avant (2), ce dernier transformant ainsi un faisceau issu dudit point image en un faisceau parallèle.
