Embodiment Construction

[0017] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.

[0018] refer to figure 1

[0019] An automatic high-definition camera monitor lens with a high-span focal length adopts an anti-long-distance structure and includes a mounting base 34. The mounting base is provided with a front mirror base 4, a middle mirror base 11, and a rear mirror base 20 connected in sequence. Three The mirror base is connected by a flange, which ensures the coaxiality, and when adjusting the lens, you only need to disassemble the flange at the corresponding joint to adjust it, which realizes convenience. The front lens group, the variable diaphragm 37, the focusing group and the filter conversion group are arranged in sequence from left to right along the incident direction of the light i...

Abstract

The invention relates to a high-span focal length automatic high-definition camera monitor lens, which belongs to the field of optoelectronic technology, and includes a front mirror base, a middle mirror base and a rear mirror base connected in sequence, and the front mirror base and the rear mirror base are along the incident direction of light From left to right, there are front mirror group, iris diaphragm, focusing group and filter conversion group, the rear part of the middle mirror base is provided with an adjustment mechanism, and the rear end of the rear mirror base is provided with a color filter The film conversion mechanism and the control mechanism located at the back of the color filter conversion mechanism. The lens is easy to install and debug, and the assembly of the lens is effectively improved.

Description

technical field [0001] The invention relates to a high-span focal length automatic high-definition camera monitor lens, which belongs to the field of optoelectronic technology. Background technique [0002] With the development of science and technology, camera monitoring technology has been widely used in national defense, industry, transportation and other fields. How to realize simple control and multi-use with less machine has become the focus of attention at present. At present, most surveillance lenses are short-focus lenses with a fixed focal length. The use of large-span focal length electric focusing lenses will be used in some occasions, the effect is far beyond the general surveillance lens, and it is easy to control, and it also reduces the number of machines to maximize efficiency. Contents of the invention [0003] The object of the present invention is to provide a high-span focal length automatic high-definition camera monitor lens, which is convenient fo...
