Title
(EN) LIGHT-ABSORBING FLANGE LENSES
(FR) LENTILLES À BRIDE ABSORBANT LA LUMIÈRE
Abstract
(EN)
Light-absorbing flange lenses that may be used in the lens stacks of compact lens systems. In a light-absorbing flange lens, the effective area of the lens is composed of a transparent optical material, and at least a portion of the flange of the lens is composed of an optical material that absorbs at least a portion of the light that enters the flange. Using light-absorbing flange lenses may allow the lens barrel to be eliminated from the lens system, thus reducing the X-Y dimensions of the lens system when compared to conventional compact lens systems that include a lens stack enclosed in a lens barrel. In addition, using a light-absorbing material in the flanges of the light-absorbing flange lenses may reduce or eliminate optical aberrations such as lens flare, haze, and ghosting in images.

La présente invention concerne des lentilles à bride absorbant la lumière qui peuvent être utilisées dans les empilements de lentilles de systèmes de lentilles compacts. Dans une lentille à bride absorbant la lumière, la zone efficace de la lentille est composée d'un matériau optique transparent et au moins une partie de la bride de la lentille est composée d'un matériau optique qui absorbe au moins une partie de la lumière qui entre dans la bride. L'utilisation de lentilles de bride absorbant la lumière peut permettre d'éliminer le tube de lentilles du système de lentilles, ce qui permet de réduire les dimensions X-Y du système de lentilles en comparaison avec des systèmes de lentilles compacts classiques qui comprennent un empilement de lentilles enfermées dans un tube de lentilles. De plus, l'utilisation d'un matériau d'absorption de lumière dans les brides des lentilles à bride absorbant la lumière peut réduire ou éliminer des aberrations optiques telles qu'un effet de flare, de trouble et de fantôme dans des images.
