The technical solution of utility model is as follows:
There is an optical lens for NEW TYPE OF COMPOSITE lens arrangement, comprise outer cylinder body (1), camera lens bayonet socket (2), semi-transparent reflective mirror (3), catoptron (4), front lens group (5) and back lens group (6);
The front end of outer cylinder body has a light inlet, and the rear end of outer cylinder body has 2 light-emitting windows, i.e. the first light-emitting window (7) and the second light-emitting window (8) of 2 light-emitting windows; Front lens group (5) and back lens group (6) are all to be arranged in outer cylinder body with the mode of outer cylinder body axes normal, and front lens group is arranged on the rear of light inlet, back lens group is arranged on the front of the first light-emitting window, includes a slice infrared filtering eyeglass in back lens group; Camera lens bayonet socket is arranged on the rearward end of outer cylinder body;
Semi-transparent reflective mirror and catoptron all tilt 45 ° to be arranged in outer cylinder body relative to the axis of outer cylinder body, and semi-transparent reflective mirror and catoptron parallel to each other; The line of the geometric center of semi-transparent reflective mirror and catoptron and the axes normal of outer cylinder body;
Extraneous light after entering from light inlet successively through front lens group and semi-transparent reflective mirror and final from second light-emitting window injection formed transmitted light path;
Extraneous light from light inlet enter rear elder generation through front lens group, again after semi-transparent reflective mirror and catoptron two secondary reflection again through back end-mirror group and final from first light-emitting window injection formed reflected light path.
Described back lens group is enlarging lens group.Enlarging lens group refers to that these eyeglasses have the function of enlarged image.
The first described light-emitting window is identical with the diameter of the second light-emitting window.
First light-emitting window is identical with the diameter of light inlet.
Described bayonet socket is provided with the contact for obtaining power supply and signal transmission.
Beneficial effect:
The optical lens with NEW TYPE OF COMPOSITE lens arrangement of the present utility model, adopt the new technology based on semi-transparent reflective mirror, introduce one piece of catoptron again, the light entering camera lens is divided into 2 bundles, the light that second light-emitting window is exported is for picture (passing through transmitted light path) overall in monitoring scene, and the image now obtained is the infrared monitoring and control image for night; And under the effect of back end-mirror group (wherein containing infrared filtering eyeglass), the image that the light that the first light-emitting window exports obtains is the natural light image amplified, be convenient to the monitoring on daytime.Therefore this optical lens with NEW TYPE OF COMPOSITE lens arrangement possesses the function of round-the-clock monitoring.
The setting of bayonet socket, for being connected fast with other devices, bayonet socket is the bayonet socket that slr camera generally adopts, and is existing mature technology.The effect of the contact on bayonet socket obtains power supply, and transmission of control signals (as controlled the signal etc. of aperture).
Therefore, this optical lens novel structure with NEW TYPE OF COMPOSITE lens arrangement, designs ingenious, is particularly useful for monitoring occasion.

Fig. 1 is the general structure schematic diagram with the optical lens of NEW TYPE OF COMPOSITE lens arrangement of the present utility model.
Fig. 2 is the rearward end structural representation of the optical lens with NEW TYPE OF COMPOSITE lens arrangement.
Label declaration: 1-outer cylinder body, 2-camera lens bayonet socket, the semi-transparent reflective mirror of 3-, 4-catoptron, 5-front lens group, 6-back lens group, 7-first light-emitting window, 8-second light-emitting window.
Embodiment
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As shown in Figure 1-2, a kind of optical lens with NEW TYPE OF COMPOSITE lens arrangement, comprises outer cylinder body 1, camera lens bayonet socket 2, semi-transparent reflective mirror 3, catoptron 4, front lens group 5 and back lens group 6;
The front end of outer cylinder body has a light inlet, and the rear end of outer cylinder body has 2 light-emitting windows, i.e. the first light-emitting window 7 and the second light-emitting window 8 of 2 light-emitting windows; Front lens group 5 and back lens group 6 are all to be arranged in outer cylinder body with the mode of outer cylinder body axes normal, and front lens group is arranged on the rear of light inlet, back lens group is arranged on the front of the first light-emitting window, includes a slice infrared filtering eyeglass in back lens group; Camera lens bayonet socket is arranged on the rearward end of outer cylinder body;
Semi-transparent reflective mirror and catoptron all tilt 45 ° to be arranged in outer cylinder body relative to the axis of outer cylinder body, and semi-transparent reflective mirror and catoptron parallel to each other; The line of the geometric center of semi-transparent reflective mirror and catoptron and the axes normal of outer cylinder body;
Extraneous light after entering from light inlet successively through front lens group and semi-transparent reflective mirror and final from second light-emitting window injection formed transmitted light path;
Extraneous light from light inlet enter rear elder generation through front lens group, again after semi-transparent reflective mirror and catoptron two secondary reflection again through back end-mirror group and final from first light-emitting window injection formed reflected light path.
Described back lens group is enlarging lens group.
The first described light-emitting window is identical with the diameter of the second light-emitting window.
First light-emitting window is identical with the diameter of light inlet.
Described bayonet socket is provided with the contact for obtaining power supply and signal transmission.
Catoptron is can only the eyeglass of reflection ray, and semi-transparent reflective mirror allows a part of ght transmission to go over, and some light reflection is gone out simultaneously, is existing mature technology, as the semi-transparent reflective mirror of the research and development of Sony.Infrared filtering eyeglass has another name called infrared-filtered sheet, for stopping that Infrared is passed through.
During practical application, the first light-emitting window and the second light-emitting window rear end are respectively provided with an imageing sensor, for obtaining 2 groups of monitoring images.
