Glass-plastic mixed lens

Abstract

The invention provides a glass-plastic mixed lens comprising a first lens, a second lens, an aperture diaphragm, a third lens, a fourth lends, a 5th lens, a 6th lens and an optical filter arranged insequence from the object side to the image side; the 1st to 4th lenses respectively refer to a spherical surface glass lens; the 5th and 6th lenses are non-spherical surface plastic lenses; the firstlens refers to a meniscus lens with a negative focal power and a convex object surface; the second lens is a meniscus lens with a positive focal power and a convex object surface; the third lens is adual-convex lens with a positive focal power; the 4th lens is a dual-concave lens with a negative focal power; the 5th lens is a lens with a positive focal power and a convex image surface; the 6th lens is a dual-concave lens with a negative focal power. The glass-plastic mixed lens employs two non-spherical surface plastic lenses to improve the imaging sharpness, thus reducing the aberration influences, obtaining better image parsing ability, and satisfying unmanned plane outdoor aerial photography needs.

Description

technical field [0001] The invention belongs to the technical field of drone lenses, and in particular relates to a glass-plastic hybrid lens. Background technique [0002] With the continuous development of drone technology, the demand for drone footage is increasing. Existing drone lenses use a large number of glass materials, and lenses made of spherical glass materials have poor image quality, low resolution, and serious distortion effects. Compared with glass materials, lenses made of plastic materials have poor thermal stability, and cannot meet the needs of drone lenses. Contents of the invention [0003] The embodiment of the present invention provides a glass-plastic hybrid lens. The lens structure is simple, which is convenient for molding and assembly. The glass-plastic hybrid lens has a lighter overall weight, which can reduce the overall weight of the drone and improve the endurance of the drone. [0004] The invention provides a glass-plastic hybrid lens, c...
