Abstract
The invention provides a novel 16-time VGA corresponding zoom lens. The novel 16-time VGA 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 diaphragm (5) and a light filter (6). The second negative lens group (2), a third positive lens group (3) and a fourth positive lens group (4) are sequentially arranged on the right side of the first positive lens group (1), the diaphragm (5) is arranged between the second negative lens group (2) and the third positive lens group (3), and the light filter (6) is arranged on the other side of the fourth positive lens group (4). The novel 16-time VGA corresponding zoom lens is simple in structure and little in constituted lenses. Aspheric surface lenses are not used, and the novel 16-time VGA corresponding zoom lens can conduct monitoring under visible light and near-infrared light and high in brightness.
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 16 times of novel VGA.
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, and therefore the camera lens that uses also being required more is the zoom lens that can both be suitable for from the visible light to the near infrared light.
In recent years for the security protection purpose, to increasing in the outdoor mounted market demands of monitor round the clock, but the eyeglass that zoom lens on the market constitutes is many, and uses spheric glass, the cost height more.
Summary of the invention
The purpose of this invention is to provide the corresponding zoom lens of a kind of 16 times of novel VGA, it is simple in structure, and it is few to constitute eyeglass, does not use aspherical lens, the zoom lens of the high brightness that 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, diaphragm 5, optical filter 6; The first positive eyeglass group's 1 right side is provided with successively between the second negative eyeglass group 2, the 3rd positive eyeglass group 3 and the 4th positive eyeglass group 4, the second negative eyeglass groups 2, the 3rd positive eyeglass group 3 and is provided with diaphragm 5, and optical filter 6 is arranged on the 4th positive eyeglass group's 4 opposite side.
The described first positive eyeglass group 1 is made of towards positive concave-convex lens one L3 of object end towards positive eyeglass one L2, the convex surface of object end negative meniscus lens one L1, the convex surface of convex surface towards the object end, negative meniscus lens one L1 and positive eyeglass one L2 gummed.
The described second negative eyeglass group 2 is by constituting towards positive concave-convex lens two L6 of object end at negative meniscus lens two L4, concave-concave eyeglass L5, the convex surface of convex surface towards the object end.
The described the 3rd positive eyeglass group 3 is by the eyeglass L7 of biconvex, and convex surface constitutes towards negative meniscus lens three L8 of imaging end.
Described four positive eyeglass groups 4 are made of towards positive eyeglass two L11 of object end towards negative meniscus lens four L10, the convex surface of object end positive concave-convex lens three L9, the convex surface of concave surface towards the object end, negative meniscus lens four L10 and positive eyeglass two L11 opposite faces be concave surface towards the imaging end, gummed mutually.
The present invention is simple in structure, and it is few to constitute eyeglass, to receiving the effective of poor revisal, does not use aspherical lens, the zoom lens of the high brightness that can monitor under visible light and near infrared light.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
With reference to Fig. 1, this embodiment 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, diaphragm 5, optical filter 6; The first positive eyeglass group's 1 right side is provided with successively between the second negative eyeglass group 2, the 3rd positive eyeglass group 3 and the 4th positive eyeglass group 4, the second negative eyeglass groups 2, the 3rd positive eyeglass group 3 and is provided with diaphragm 5, and optical filter 6 is arranged on the 4th positive eyeglass group's 4 opposite side.
The described first positive eyeglass group 1 is made of towards positive concave-convex lens one L3 of object end towards positive eyeglass one L2, the convex surface of object end negative meniscus lens one L1, the convex surface of convex surface towards the object end, negative meniscus lens one L1 and positive eyeglass one L2 gummed.
The described second negative eyeglass group 2 is by constituting towards positive concave-convex lens two L6 of object end at negative meniscus lens two L4, concave-concave eyeglass L5, the convex surface of convex surface towards the object end.
The described the 3rd positive eyeglass group 3 is by the eyeglass L7 of biconvex, and convex surface constitutes towards negative meniscus lens three L8 of imaging end.
Described four positive eyeglass groups 4 are made of towards positive eyeglass two L11 of object end towards negative meniscus lens four L10, the convex surface of object end positive concave-convex lens three L9, the convex surface of concave surface towards the object end, negative meniscus lens four L10 and positive eyeglass two L11 opposite faces be concave surface towards the imaging end, gummed mutually.
This embodiment is simple in structure, and it is few to constitute eyeglass, to receiving the effective of poor revisal, does not use aspherical lens, the zoom lens of the high brightness that can monitor under visible light and near infrared light.
