Abstract

A photographing optical lens includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element has positive refractive power. The second lens element, the third lens element, and the fourth lens element have refractive power. The fifth lens element with negative refractive power has an aspheric object-side surface and an aspheric image-side surface being concave in a paraxial region thereof. The sixth lens element with negative refractive power has an aspheric object-side surface being concave in a paraxial region thereof and an aspheric image-side surface being concave in a paraxial region thereof, wherein the image-side surface thereof has at least one inflection point. The photographing optical lens further includes a stop located between an object and the second lens element.

Description

RELATED APPLICATIONS[0001]This application claims priority to Taiwan Application Serial Number 103122671, filed Jul. 1, 2014, which is herein incorporated by reference.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to a photographing optical lens. More particularly, the present disclosure relates to a compact photographing optical lens applicable to electronic devices.[0004]2. Description of Related Art[0005]In recent years, with the popularity of electronic devices having camera functionalities, the demand of miniaturized optical systems has been increasing. The sensor of a conventional optical system is typically a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor) sensor. As the advanced semiconductor manufacturing technologies have allowed the pixel size of sensors to be reduced and compact optical systems have gradually evolved toward the field of higher megapixels, there is an increasing demand for compact optical systems fe...
