Abstract
Official abstract text for this publication.
An imaging lens which uses a larger number of constituent lenses for higher performance and features a low F-value, low-profile design and a wide field of view. Designed for a solid-state image sensor, the imaging lens includes constituent lenses arranged in order from an object side to an image side: a first positive refractive power lens having a convex object-side surface; a second negative refractive power lens having a concave image-side surface; a third positive refractive power lens having a convex image-side surface; a fourth negative refractive power lens having a concave image-side surface; a fifth positive refractive power lens as a meniscus lens having a convex image-side surface; a sixth lens as a meniscus double-sided aspheric lens having a concave image-side surface near an optical axis; and a seventh negative refractive power lens as a double-sided aspheric lens having a concave image-side surface near the optical axis.
First claim
Opening claim text (preview).
What is claimed is: 1. An imaging lens in which elements are arranged in order from an object side to an image side, comprising: a first lens with positive refractive power having a convex surface on the object side near an optical axis; a second lens with negative refractive power having a concave surface on the image side near the optical axis; a third lens with positive refractive power having a convex surface on the image side near the optical axis; a fourth lens with ne…
