Specific embodiment
Embodiment 1
Fig. 1, including the lens group 120 of refracting-reflecting lens group 110 and first are referred to according to a kind of implementation method of panoramic optical camera lens of the invention.
Herein, described using " preceding surface " and " surface afterwards " along two surfaces that optical axis direction is relative on an optical mirror slip, wherein, the surface that incident light is first passed through is referred to as preceding surface, after by surface be referred to as after surface.In refracting-reflecting lens group, there is reflection due to, incident light may repeatedly pass through some surfaces, and order when " preceding surface " and " surface afterwards " is passed through first with incident light is defined.
Refracting-reflecting lens group 110 includes two catadioptric mirrors glued together, i.e. the first catadioptric mirror 111 and the second catadioptric mirror 112, and this cemented doublet not only processes simple but also superior performance.The central area on the preceding surface of the first catadioptric mirror is reflector space 1111, and remaining region is regional transmission.The rear surface of the first catadioptric mirror is together with the preceding surface bonding of the second catadioptric mirror and is regional transmission.The central area on the rear surface of the second catadioptric mirror is regional transmission, and remaining region is reflector space 1121.In other embodiments, the need for according to optical design, the first catadioptric mirror and the second catadioptric mirror can not also it is glued and together with being simply brought into close contact.
As shown in Figure 1, incident ray is injected from the regional transmission on the preceding surface of the first catadioptric mirror, then pass through the rear surface of the first catadioptric mirror and the preceding surface of the second catadioptric mirror, then reflected by the reflector space on the rear surface of the second catadioptric mirror, then the preceding surface of the second catadioptric mirror and the rear surface of the first catadioptric mirror are again passed through, then reflected by the reflector space on the preceding surface of the first catadioptric mirror, then third time then passes through the regional transmission injection on the rear surface of the second catadioptric mirror through the rear surface of the first catadioptric mirror and the preceding surface of the second catadioptric mirror.Therefore, the overall diopter of refracting-reflecting lens group is being for just, wherein, the diopter of the first catadioptric mirror may be configured as negative and the diopter of the second catadioptric mirror may be configured as just.
Because the preceding surface of the first catadioptric mirror and the rear surface of the second catadioptric mirror are divided into two regions of reflection and transmission, therefore whole surface both can be the compound curved surface constituted using the simple surface of single curved-surface shape, or by different curve form.For example, the preceding surface of the first catadioptric mirror can be simple convex surface, or compound curved surface, for example for convex surface, reflector space is plane or concave surface or the convex surface different from the curved-surface shape of regional transmission to its regional transmission.Similarly, the rear surface of the second catadioptric mirror can be simple convex surface, or compound curved surface, and for example for convex surface, regional transmission is plane or concave surface or the convex surface different from the curved-surface shape of reflector space to its reflector space.Alleged convex surface or concave surface can be specifically sphere or aspherical, such as conical surface or other secondary or high-order curved surfaces etc..The rear surface of the first catadioptric mirror（That is the preceding surface of the second catadioptric mirror）Can be then convex surface, concave surface or plane etc..

It is aspherical preferably by the preceding surface of the first lens 121 and back surface design to take into account excellent systematic function and relatively low difficulty of processing in the present embodiment, and is sphere by the preceding surface of other lenses and back surface design.Certainly, because plane can be considered that radius of curvature is infinitely great sphere, therefore alleged sphere also includes plane.The alleged aspherical even aspheric surface curved surface that can for example use as described by following formula：
z=cr2/(1+√(1-(1+k)c2r2))+a1r2+a2r4+a3r6+a4r8+a5r10+…
Wherein, z is aspherical with each and the intersection point of optical axis is as starting point, and in the axial direction value on the direction of optical axis, k is quadratic surface coefficient, and c is the curvature of centre of lens surface；R is the height of lens surface, a1, a2, a3, a4, a5... it is asphericity coefficient.Can be by the aspherical astigmatism and aberration to correct whole optical system of the first lens, on the one hand cause that whole optical system has small astigmatism and imaging aberrations are also relatively uniform, with excellent image quality, on the other hand cause that whole optical system has low complexity and processing sensitivity, effectively reduce holistic cost.
As one kind preferred embodiment, in the present embodiment, the aperture (Aperture) of panoramic optical camera lens is arranged at the position of the regional transmission on the rear surface of the second catadioptric mirror.It is herein the optimum position that aperture is set, can farthest reduces because of the veiling glare that the reflection of lens group causes.
