`ABSTRACT
`This invention provides a photographing optical lens assem
`bly, from an object side to an image side in order, comprising
`a first lens element with positive refractive power having a
`convex object-side Surface, a second lens element with nega
`tive refractive power having a concave image-side Surface, a
`third lens element with positive refractive power, a fourth lens
`element with negative refractive power having a concave
`image-side surface, both the two surfaces of the fourth lens
`thereof being aspheric. And an aperture stop is positioned
`between the first element and the second lens element. There
`are four lens elements with refractive power in the lens assem
`bly.

`PHOTOGRAPHING OPTICAL LENS
`ASSEMBLY
`
`BACKGROUND OF THE INVENTION
`1. Field of the Invention
`0001
`0002 The present invention relates to a photographing
`opticallens assembly, and more particularly, to a photograph
`ing optical lens assembly with reduced optical sensitivity and
`high resolution.
`0003 2. Description of the Prior Art
`0004. A conventional high resolution compact photo
`graphing optical lens assembly is generally configured Such
`that a frontal aperture stop is adopted and there are four lens
`elements in the assembly, wherein the first lens element and
`the second lens element with spherical Surfaces made of glass
`are usually combined together into a doublet lens structure in
`order to correct chromatic aberrations. This is disclosed in
`U.S. Pat. No. 7,365,920 and there are drawbacks with this
`method. First, an arrangement of too many spherical lenses
`will limit the freedom in optical system design, which makes
`it difficult to shorten the total track length of the system.
`Secondly, the bonding of glass lenses is difficult in manufac
`turing process. A lens assembly with four independent lenses
`is disclosed in U.S. Pat. No. 7.277,238, including multiple
`aspheric lenses which effectively shorten the total track
`length of the system and obtaining good image quality. How
`ever, due to the aperture stop of the system is positioned in
`front of the first lens element, the system sensitivity is
`increased which also increases the difficulty in controlling the
`yields in manufacturing.

`
`between the object-side surface of the first lens element and
`the electronic sensor is TTL, and they satisfy the relations:
`
`0008 Such an arrangement of optical elements can effec
`tively reduce the total track length of the lens assembly, lower
`the sensitivity of the optical system, and obtain higher reso
`lution image quality.
`0009. In the aforementioned photographing optical lens
`assembly, the first lens element with positive refractive power
`supplies refractive power for the system and reduces the total
`track length of the system; the second lens element with
`negative refractive power may correct the chromatic aberra
`tion of the system; the third lens element with positive refrac
`tive power can effectively distribute the refractive power of
`the first lens element and reduce the sensitivity of the system;
`the fourth lens element with negative refractive power acts as
`a corrective lens, which can balance and correct the various
`aberrations in the system.
`0010. In the aforementioned photographing optical lens
`assembly of the present invention, the first lens element can
`be a bi-convex lens element or a meniscus lens element hav
`ing a concave object-side Surface and a convex image-side
`surface. When the first lens element is a bi-convex lens ele
`ment, the refractive power thereof can be effectively
`enhanced, thus shortening the total track length of the system.
`When the second lens element is a meniscus lens element
`with a convex object-side Surface and a concave image-side
`surface, the spherical aberration of the system can be cor
`rected more favorably. When the image-side surface of the
`second lens element is concave, Petzval Sum of the system
`can be effectively corrected and the back focal distance of the
`system can be enlarged to obtain enough back focal distance
`for placing other components in the photographing optical
`lens assembly. When the second lens element is a bi-convex
`lens element, chromatic aberration of the system can be favor
`ably corrected with the corresponding choice of materials.
`When the second lens element is a meniscus lens element
`with a convex object-side Surface and a concave image-side
`Surface, astigmatism of the system can be favorably cor
`rected, and the sensitivity of the system can be reduced. When
`the third lens element has a concave object-side Surface and a
`convex image-side surface, high order aberration can be
`favorably corrected. The fourth lens element can be a bi
`concave lens element or a meniscus lens element with a
`convex object-side Surface and a concave image-side Surface.
`When the fourth lens element is a bi-concave lens element,
`the principal point of the optical system can be further away
`from the image plane, which reduces the total track length of
`the system in order for the system to stay compact. When the
`fourth lens element has a convex object-side Surface and a
`concave image-side Surface, astigmatism and high order aber
`rations of the system can be favorably corrected.
`0011. In the aforementioned photographing optical lens
`assembly, the aperture stop is disposed between the first lens
`element and the second lens element. By providing positive
`refractive power from the first and third lens elements, while
`the aperture stop is disposed closer to the object side of the
`photographing optical lens assembly, the total track length of
`the photographing optical lens assembly can
