Abstract
A novel 16x VGA corresponding zoom lens includes 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 filter (6), wherein the second negative lens group (2), the third positive lens group (3) and the fourth positive lens group (4) are successively arranged on a right side of the first positive lens group (1); the diaphragm (5) is mounted between the second negative lens group (2) and the third positive lens group (3) and the filter (6) is disposed on the other side of the fourth positive lens group (4). The zoom lens has a simple structure, is few in composing lenses without aspheric lenses, is high in brightness and can monitor in visible light and near-infrared light.
Description
Technical field
The utility model relates to the zoom lens technology field, is 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 be all the video camera of dual-purpose day and night, this type of video camera is mainly 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 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 forms is many, and uses spheric glass more, and cost is high.
Summary of the invention
The purpose of this utility model is to provide the corresponding zoom lens of a kind of 16 times of novel VGA, and it is simple in structure, forms eyeglass few, 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 utility model 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 negative eyeglass group 2 of positive eyeglass group 4, the second, 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 consists 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 at negative meniscus lens two L4s, concave-concave eyeglass L5, the convex surface of convex surface towards the object end, towards positive concave-convex lens two L6 of object end, forming.
The described the 3rd positive eyeglass group 3 is by the eyeglass L7 of biconvex, and convex surface forms towards negative meniscus lens three L8 of imaging end.
The described the 4th positive eyeglass group 4 consists 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 utility model is simple in structure, forms eyeglass few,, 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 utility model.
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 negative eyeglass group 2 of positive eyeglass group 4, the second, 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 consists 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.
