Abstract
The invention relates to the technical field of zoom lenses, in particular to a novel 30-time 720P corresponding zoom lens. The novel 30-time 720P corresponding zoom lens comprises a first positive lens group (1), a second negative lens group (2), a third positive lens group (3), a fourth positive lens group (4), a fifth negative lens group (5) and a diaphragm (6). The second negative lens group (2), the third positive lens group (3), the fourth positive lens group (4) and the fifth negative lens group (5) are sequentially arranged on the left side of the first positive lens group (1). The diaphragm (6) is arranged between the second negative lens group (2) and the third positive lens group (3). The novel 30-time 720P corresponding zoom lens is simple in structure, smaller in size, wide in angle and high in magnification, has the zooming ratio of 25-30 times approximately, and can achieve monitoring under visible light and near-infrared light.
Description
Technical field
The present invention relates to the zoom lens technology field, be specifically related to the corresponding zoom lens of a kind of 30 times of novel 720P.
Background technology
At present, in the monitoring field, exploitation all be the video camera of dual-purpose day and night.This type of video camera mainly is to monitor with visible light daytime, monitor with near infrared light night, therefore the camera lens that uses also being required more is the high magnification zoom lens that can both be suitable for from the visible light to the near infrared light, make complexity from visible light to the near infrared light high magnification, and multiplying power is regulated limited.
Summary of the invention
The purpose of this invention is to provide the corresponding zoom lens of a kind of novel 30 times of 720P, it is simple in structure, the zoom lens that provide a kind of more small-sized, wide-angle, about 25 ~ 30 times of powerful zoom ratios, can monitor under visible light and near infrared light.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises the first positive eyeglass group 1, the second negative eyeglass group 2, the 3rd positive eyeglass group 3, the 4th positive eyeglass group 4, the 5th negative eyeglass group 5, diaphragm 6, the described first positive eyeglass group's 1 left side is disposed with between the second negative eyeglass group 2, the 3rd positive eyeglass group 3, the 4th positive eyeglass group 4, the 5th negative eyeglass group 5, the second negative eyeglass groups 2 and the 3rd positive eyeglass group 3 and is provided with diaphragm 6.
The described first positive eyeglass group 1 is made up of negative concave and convex lenses L1, biconvex mirror L2, the first positive concave and convex lenses L3, the second positive concave and convex lenses L4.
The described second negative eyeglass group 2 is made up of concave-concave eyeglass L5, negative concave and convex lenses L6.
The described the 3rd positive eyeglass group 3 is made up of convex lens sheet L7, negative concave and convex lenses L8.
The described the 4th positive eyeglass group 4 is made up of concave-concave convex lens L9, negative concave and convex lenses L10.
The described the 5th negative eyeglass group 5 biconvex mirror L11, negative concave and convex lenses L12 form.
The present invention has following beneficial effect: it is simple in structure, the zoom lens that provide a kind of more small-sized, wide-angle, about 25 ~ 30 times of powerful zoom ratios, can monitor under visible light and near infrared light.
