Embodiment Construction

[0040] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0041] figure 1 is a structural diagram of a compact ultra-wide-angle imaging optical system according to a first exemplary embodiment of the present disclosure.

[0042] The first lens indicates the lens closest to the object side, and the sixth lens indicates the lens closest to the image sensor. In each lens, the first surface means the surface facing the object side (or the object side surface), and the second surface means the surface facing the image side (or the image side surface). In this specification, the numerical value of the radius of curvature, the numerical value of the thickness, and the numerical value of the thickness of the lens may all be mm.

[0043] According to the compact ultra-wide-angle imaging optical system of the present disclosure, it is composed of a first lens L1, a second lens L2, a third lens L3, a fourth lens...

Abstract

The invention relates to a compact ultra-wide-angle imaging optical system being composed of a negative first lens, a positive second lens, a negative third lens, a positive fourth lens, a positive fifth lens and a negative sixth lens in sequence from the object side to the image side. A diaphragm is arranged between the first lens and the second lens, and the second lens and the third lens are glued. According to the compact ultra-wide-angle imaging optical system, the field angle reaches up to 116 degrees, and miniaturization and an ultra-wide angle can be achieved.

Description

technical field [0001] The invention relates to an imaging optical system, in particular to a six-piece compact ultra-wide-angle imaging optical system. Background technique [0002] At present, the imaging optical system has been widely used, and its performance has been gradually improved. However, the existing imaging optical system still has many shortcomings, and further improvement is needed in terms of miniaturization and wide-angle. Contents of the invention [0003] The invention provides a compact ultra-wide-angle imaging optical system, hoping to further realize miniaturization and increase the viewing angle. [0004] According to the compact ultra-wide-angle imaging optical system of the present disclosure, it is composed of a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in sequence from the object side to the image side; Located between the first lens and the second lens. And the imaging optical system further include...
