Abstract
Official abstract text for this publication.
Disclosed is an optical system. The optical system includes first to fifth lenses sequentially arranged from an object side to an image side. The optical system satisfies 1.5<n 2 <1.55, 50<v 2 <70, and 20<v 3 <30 in which n 2 represents a refractive index of the second lens, v 2 represents an abbe number of the second lens, and v 3 represents an abbe number of the third lens.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical system comprising, in order from an object side to an image side: a first lens in a meniscus shape having a convex surface on an object side of an optical axis of the first lens; a second lens in a meniscus shape having a concave surface on an object side of an optical axis of the second lens; a third lens having a biconcave shape at an optical axis of the third lens; a fourth lens in a meniscus shape having a concave surface on an object si…
