Ultrahigh-definition wide-angle vehicle-mounted lens

Abstract

The invention discloses an ultrahigh-definition wide-angle vehicle-mounted lens which comprises a lens barrel, a mounting position of an optical filter is arranged at the rear end of the lens barrel, the optical filter is mounted in the mounting position in an adhesive mode, a lens cavity penetrating through the lens barrel is further formed in the lens barrel, a step is arranged at the position, close to the optical filter, of the lens cavity, and a first aspheric lens is arranged at the position, matched with the step, in the lens cavity. In the lens cavity, the front end of the first aspheric lens is spaced with the second plastic aspheric lens through the first SOMA sheet, and the front end of the second aspheric lens is spaced with the third lens through the second SOMA sheet. The front end of the third lens is assembled with a fourth lens through a first space ring, the fourth lens and a fifth lens are spaced by a second SOMA, a first step is manufactured at the front end of the lens cavity, an arc-shaped lens is assembled on the first step in a sealing mode through a waterproof rubber ring, and the arc-shaped lens is fixed relative to a lens barrel cover buckle through a lens cover arranged in front of the lens barrel; the optical filter is matched with the lens cover and the arc-shaped lens to seal the lens cavity, and the aspheric first lens, the aspheric second lens, the third lens, the fourth lens and the fifth lens are matched and assembled in the lens cavity in a sealing mode to form a matched lens.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to an ultra-high-definition wide-angle vehicle-mounted lens. Background technique [0002] At present, with the development of high-pixel chips, the chip pixels are getting higher and higher, and the required lens resolution is also getting higher and higher. At the same time, the angle is required to be large enough. In order to solve these problems, more and more lenses are designed for the lens, and the requirements for the design of the lens are getting higher and higher, resulting in an increase in cost and an increase in the total optical length. [0003] Currently, aspherical lens designs made of plastic materials are generally used, but the image quality of lenses designed only with aspheric lenses made of plastic materials is not stable. Because plastic materials are not good in heat resistance, acid resistance and alkali resistance, the image quality of the lens ten...

[0004] Our last patent application: CN201821485756.X A high-definition automotive rearview lens, which discloses a high-definition automotive lens with easy assembly, large viewing angle, small deformation distortion and image deformation, and large hydrophobic angle. High-definition, the horizontal angle of shooting is greater than 190 degrees, using aspherical molded glass, the distortion is small, the surface of the lens is coated with a hydrophobic film, and the technical effect of the hydrophobic angle is greater than 95 degrees, but the distortion of this technical solution is not small enough, and there is still a lack of heat dissipation good question
