Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera lens and a camera. Background Art

[0002] With the advancement of technology and the diversification of people's aesthetic tastes, photography and videography are no longer just a means of recording reality, but have become a form of artistic creation and personal expression. In this context, higher requirements are placed on the optical effects of camera lenses, and people are beginning to pursue a richer and more unique visual experience.

[0003] As a rare and beautiful atmospheric optical phenomenon, the bright spots on both sides of the sun not only bring visual shock to people, but also inspire the creation of photographers and artists. Applying the sun dog effect to the camera lens can create images with dreamy colors and artistic sense, adding unique artistry and interest to photography and video works.

[0004] However, existing camera lens designs mainly focus on basic imaging qualities such as clarity, contrast and color reproduction, and capture images through the principles of refraction and reflection. Although these traditional optical designs have achieved a fairly high level of imaging quality, they are still unable to simulate special optical phenomena.

[0005] Therefore, it is necessary to improve the existing camera lenses to overcome the defects of the prior art. Utility Model Content

[0006] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a camera lens to solve the problem that the prior art cannot simulate special optical phenomena.

[0007] A camera lens comprises a circular lens base, wherein the circular lens base comprises a first mirror surface and a second mirror surface, wherein the first mirror surface is provided with an annular prism, the cross section of the annular prism is an isosceles triangle, the annular prism comprises a waist surface and a bottom surface, the bottom surface is connected to the first mirror surface, and an anti-reflection coating is provided on the second mirror surface.

[0008] Preferably, the annular prism is in the shape of a circular ring or an elliptical ring.

[0009] The circular ring prism can better match the circular lens base to form a more uniform and beautiful sundog effect.

[0010] The elliptical ring prism can match the rectangular photosensitive element to ensure the sundog effect in the final image.

[0011] Preferably, the height of the annular prism is 0.5 mm to 2 mm, and the length of the base is 1 mm to 4 mm.

[0012] Preferably, the vertex angle of the annular prism is 50 degrees to 60 degrees.

[0013] Annular prisms within this angular range are able to refract light effectively, creating clear, well-separated sundogs while avoiding excessive obstruction of the main image.

[0014] Preferably, the inner diameter of the annular prism is 1 / 2 to 2 / 3 of the diameter of the circular lens base.

[0015] This inner diameter range can ensure the sundog effect while reserving enough area in the central region for normal imaging, thereby reducing obstruction of the main image.

[0016] Preferably, a plurality of the annular prisms are provided, and the plurality of the annular prisms are arranged along the circumferential direction of the circular lens base, and a gap is provided between two adjacent annular prisms, and the width of the gap gradually increases along the circumferential direction.

[0017] The gradually increasing gap width can further suppress the diffraction effect, reduce stray light, and create a softer, more natural sundog effect.

[0018] Preferably, the width of the gap is between 0.2 mm and 1 mm.

[0019] This gap width range can effectively balance the diffraction effect and the sundog effect, ensuring a natural transition between image clarity and the sundog effect.

[0020] The second object of the utility model is to provide a camera, which includes a camera lens as described above. The camera can capture images with unique sundog effects, add artistry and interest to photography and videography, and meet users' needs for novel optical effects.

[0021] The beneficial effects of the utility model are:

[0022] The utility model provides a camera lens, which can generate a symmetrical sundog effect on both sides of a shooting picture by arranging an annular prism on the first mirror surface of the lens base, so that light enters from the two side surfaces of the annular prism and is emitted from the bottom surface after being refracted by the annular prism. At the same time, the anti-reflection coating on the second mirror surface can reduce light reflection, increase light transmittance, and improve imaging quality. BRIEF DESCRIPTION OF THE DRAWINGS
