Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, the present invention has an equal-thickness 3mm Datong optical zero-temperature-drift optical structure, including a front group of lenses A, a diaphragm C, and a rear group of lenses B that are sequentially arranged along the incident direction of light from left to right, and the front group of lenses A It includes a meniscus negative lens A1, a biconcave negative lens A2, and a biconvex positive lens A3 arranged in sequence from left to right; A cemented group consisting of lens B2 and meniscus negative lens B3 in close contact, and biconvex positive lens B4.

[0023] In this embodiment, the air gap between the front lens group A and the rear lens group B is 2.7mm.

[0024] In this embodiment, the air interval between the meniscus negative lens A1 and the biconcave negative lens A2 is 3.2mm, and th...

Abstract

The invention relates to a uniform-thickness 3mm high-light-transmission zero-temperature-drift optical structure and an imaging method thereof. The uniform-thickness 3mm high-light-transmission zero-temperature-drift optical structure comprises a front lens group A, a diaphragm C and a rear lens group B which are successively arranged in an incident direction of light from left to right, whereinthe front lens group A comprises a crescent concave lens A1, a biconcave minus lens A2 and a biconvex plus lens A3 which are arranged successively from left to right; the rear lens group B comprises acrescent plus lens B1, a gluing assembly and a biconvex plus lens B4 which are arranged successively from left to right; and the gluing assembly consists of a biconvex plus lens B2 and a crescent minus lens B3 which are closely connected. The uniform-thickness 3mm high-light-transmission zero-temperature-drift optical structure is reasonable in structural design, large in luminous flux, low in sensitivity and low in day and night defocusing, the image quality is improved under the conditions of high and low temperatures, and zero temperature drift is realized really.

Description

Technical field: [0001] The invention relates to an optical structure with an equal thickness of 3 mm and a zero temperature drift optical structure and an imaging method thereof. Background technique: [0002] Lens is an important part of security cameras. After years of development, security lenses have gradually transitioned from low-end products with multiple lenses, high assembly difficulty, and low optical indicators to economical high-level security lenses. However, most lenses currently on the market still have problems such as small light transmission, large day and night defocus, high and low temperature sensitivity, and low illumination. When this type of lens is used with a camera, it is difficult to truly achieve high resolution and confocal day and night. Invention content: [0003] The object of the present invention is to address the above deficiencies, to provide an equal-thickness 3mm large-pass light zero-temperature-drift optical structure and its imag...
