IMAGING LENS, CAMERA MODULE, AND PORTABLE TERMINAL APPARATUS
摘要:
An imaging lens comprises, in order from an object side: a first lens having a positive refractive power and a meniscus shape and having a convex surface directed to the object side; a second lens having a negative refractive power in the vicinity of an optical axis of the imaging lens; and a third lens having a positive refractive power in the vicinity of the optical axis, wherein at least one surface of each of the second lens and the third lens is an aspheric surface; and the imaging lens satisfies the following conditional expression expressions: 0.7
