Abstract
The utility model relates to the technical field of optical lens manufacture, in particular to an amplification lens adaptive to a wide-angle high-power zoom lens, which consists of a negative power front lens group A and a positive power back lens group B; along the direction of the incidence of light, the front lens group A is provided with a negative crescent lens A1 and a pair of concave lenses A2 which are arranged at interval in sequence, the positive power back lens group B is provided with two pairs of convex lenses B1, B2 which are arranged at interval in sequence, light is reflected by the front lens group A and then is imaged on the back focal plane of the front lens group A, the back focal plane of the front lens group A is also the front focal plane of the back lens group B, and the light is then reflected by the back lens group B and then enters a main objective lens C. The amplification lens is not only adaptive to the high-resolution wide-angle zoom lens with zoom ratio of larger than 10 times, and angle of vision on the wide-angle end of larger than 75 degrees, amplifies the angle of vision of the wide-angle high-power zoom lens, and in addition, during the high-power zooming process of the zoom lens, the imaging resolution of the system can not reduce, the image is not sliced and does not distort, and the imaging effect is good.
Description
Technical field
The utility model relates to optical lens manufacturing technology field, the particularly a kind of and adaptive amplification mirror of wide-angle high-power zoom lens.
Background technology
In traditional camera, digital camera or application television camera system, amplification mirror is widely used.In the prior art, amplification mirror mostly adopts structural shape as shown in Figure 3, the amplification mirror of this kind structural shape only can with focus apart from camera lens or low power zoom lens adapted, and can be adaptive the field angle of camera lens all smaller, obviously after it increased expansion, the field angle of imaging system also can't reach the level of wide-angle.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and the adaptive amplification mirror of wide-angle high resolving power high-power zoom lens, this amplification mirror not only helps enlarging the field angle of wide-angle high-power zoom lens, and in the high power zoom process of zoom lens, imaging effect is good.
For achieving the above object, the technical solution of the utility model is: a kind of and adaptive amplification mirror of wide-angle high-power zoom lens, it is characterized in that: constitute by the preceding mirror group A of negative power and the back mirror group B of positive light coke, along the light incident direction, mirror group A is provided with a negative crescent moon eyeglass A1 and a biconcave mirror sheet A2 of space successively before described, described back mirror group B is provided with two biconvex eyeglass B1 of space successively, B2, light is imaged on the back focal plane of described preceding mirror group A after the mirror group A refraction before described, the back focal plane of mirror group A be the front focal plane of described back mirror group B simultaneously before described, light again after described mirror group B reflect the laggard object lens C that becomes owner of.
The beneficial effects of the utility model are the new structure designs by this amplification mirror lens set, the focal power of having disperseed amplification mirror, increased the factor of aberration correction, when increasing field angle, the off-axis aberration of corrective system, the principal goods mirror that makes the hypermutation multiple proportions is in the zoom overall process, the imaging definition of system does not descend, and image do not cut, undistorted, and imaging effect is good, thereby filled up the market vacancy in this field, had wide market application prospect.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Embodiment
Of the present utility model and the adaptive amplification mirror of wide-angle high-power zoom lens, as Fig. 1, shown in Figure 2, constitute by the preceding mirror group A of negative power and the back mirror group B of positive light coke, along the light incident direction, mirror group A is provided with the negative crescent moon eyeglass A1 and the concave-concave eyeglass A2 of space successively before described, described back mirror group B is provided with two biconvex eyeglass B1 of space successively, B2, light is imaged on the back focal plane of described preceding mirror group A after the mirror group A refraction before described, the back focal plane of mirror group A overlaps with the front focal plane of described back mirror group B before described, thereby light after the mirror group B refraction, enters principal goods mirror C with parallel rays after described again.
In the present embodiment, airspace before described between mirror group A and the described back mirror group B is 2.52mm, airspace between described negative crescent moon eyeglass A1 and the concave-concave eyeglass A2 is 10.79mm, and the airspace among the described back mirror group B between two biconvex eyeglass B1, the B2 is 5.82mm.
The focal length of mirror group A is-35.9mm before above-mentioned, and the focal length of described back mirror group B is 49.8mm, and the visual field increases expansion rate β can reach 1.3 times.
Fig. 3 is in the prior art and focuses distance or the light path synoptic diagram of the amplification mirror that the low power zoom lens is adaptive.As can be seen from the figure, embodiment of the present utility model (Fig. 1, shown in Figure 2) has tangible difference with the structural shape of this amplification mirror, the utility model being distributed rationally and designing by each mirror group, make the amplification mirror of the present utility model can be suitable with wide-angle, high-resolution, high-power zoom lens, thereby it is supporting with the video camera system that with CCD or CMOS is photoelectric sensor, the field angle of camera system is increased, and in principal goods mirror varifocal overall process, do not cause the sharpness of imaging to descend, do not cause image cutting, distortion.This amplification mirror can adaptive change multiple proportions greater than 10 times, the wide-angle side field angle is greater than 75 ° high-resolution zoom pick-up lens, make the field angle of wide-angle side expand as 98 °, it is 1.3 times that the visual field increases the expansion rate, system imaging resolution after adaptive is better than 2,000,000 pixels, improves the purpose that the zoom lens becomes multiple proportions thereby reach.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
