Abstract
The embodiment of the invention discloses an optical system with a high pixel, a large target area, a large aperture and an ultra wide angle. According to the optical system, a first optical lens, a second optical lens, a third optical lens, a fourth optical lens, a fifth optical lens and a sixth optical lens are arranged along an optical axis from an object surface to an image surface in sequence; the focal power of the first optical lens is negative; the focal power of the second optical lens is negative; the focal power of the third optical lens is negative; the focal power of the fourth optical lens is positive; the focal power of the fifth optical lens is positive; the focal power of the sixth optical lens is negative; in addition, the optical total length TTL of the optical system meets the condition that TTL is larger than or equal to 20 mm and is smaller than or equal to 28 mm. According to the embodiment, the optical system is mainly formed by six optical lenses, the number oflenses is small, and the optical system is simple in structure and low in cost; different optical lenses are adopted and mutually combined, the focal power is reasonably distributed, the chromatic aberration and temperature effect of the system can be effectively compensated, and the optical system has good optical performance such as large target area, large aperture, good resolving power, little distortion, excellent temperature performance and the like.
Description
Technical field: [0001] The invention relates to an optical system, in particular to an ultra-wide-angle optical system with high pixels, large target surface and large aperture. Background technique: [0002] All-glass optical systems currently used in electronic products generally have defects such as low resolution, severe purple fringing in large aperture optical systems, and poor temperature effects. At the same time, the high-pixel and large-target optical system usually adopts a structure above 8G, which has problems such as high cost, small aperture, and low light transmission. Invention content: [0003] In order to overcome the common problems of low resolution, serious purple fringing, and poor temperature effect in existing optical systems, an embodiment of the present invention provides an ultra-wide-angle optical system with high pixels, large target surface, and large aperture. [0004] High-pixel, large-target, large-aperture, ultra-wide-angle optical syst...
