Abstract
The utility model discloses an optical focusing system including a focusing lens group, a fixed lens group and an optical system structure composed of imaging faces. The focusing lens group is arranged on the utmost front end of an object party, the utmost rear end of an image party or between lenses of the fixed lens group. The optical focusing system has advantages of being short in focusing distance, small in size, high in practicability and the like and can realize high-definition precise focusing quickly. The optical focusing system can be applied to a high-definition video monitoring camera lens or a camera lens of a high-end intelligent cell phone.
Description
[technical field]
The utility model relates to a kind of optical focusing system, relates in particular to a kind of fast automatic focusing system of small-sized cameras with fixed focus structure.
[background technology]
Along with the fast development of imaging technique, require more and more higher to the image quality of pick-up lens.Wherein, require the resolution of imaging high on the one hand, from 2,000,000,5,000,000 pixels, to the even above resolution of 1,000 ten thousand pixel of 800 pixels, require on the other hand camera overall volume little, meet the requirement that easy to install and smart mobile phone is convenient for carrying, outward appearance is slim of monitoring camera.On the other hand, also require the camera can blur-free imaging in camera distance on a large scale, this just requires Minitype taking lens to have focusing function.
The existing pick-up lens with focusing function, due to optical system structure, while taking close shot and distant view, need camera lens entirety focusing mobile, and focusing mobile distance is longer.In the time being applied in high-definition video monitoring field, while taking on a large scale scene, more than focussing distance reaches 0.5mm, cause the focusing time long, can not certain specific monitored picture of real-time grasp shoot; In the time that it is applied to smart mobile phone pick-up lens, focusing mobile distance reaches 0.2-0.5mm, and the large and focusing accuracy of lens focusing assembly profile is reduced, and can not meet the request for utilization of the slim and high definition imaging of smart mobile phone outward appearance.
[utility model content]
The utility model is the problem that solves above-mentioned existence, thereby proposed one, to have focussing distance short, can realize quick high definition and accurately focus, and overall volume is little, practical optical focusing system, may be used on high-definition video monitoring pick-up lens and high-end smartphones pick-up lens.
The utility model is by the following technical solutions:
A kind of optical focusing system, is characterized in that comprising focusing lens set 1, fixing len group 2, and the optical system structure that forms of imaging surface 3, described focusing lens set 1 is arranged on object space foremost, or the rearmost end of image space is set, or is arranged between each lens of fixing len group 2.
Optical focusing system as above, the lens that it is characterized in that described focusing lens set 1 and fixing len group 2 are sphere or are non-spherical lens.
Optical focusing system as above, is characterized in that being provided with optical filter 4 towards the one side of object space before imaging surface 3.
Optical focusing system as above, is characterized in that described focusing lens set is a slice lens composition, or two or more lens composition.
Optical focusing system as above, is characterized in that described fixing len group is a slice lens composition, or two or more lens composition.
The beneficial effects of the utility model:
1, this optical lens has been realized the following short distance focusing mobile of 0.10mm.
2, the application of this optical lens and monitoring camera, can realize the imaging of video monitoring system rapid focus high definition
3, this optical lens is applied to intelligent shooting mobile phone, can realize cell phone appearance slim, focusing precision high.

Fig. 1 is scheme one schematic diagram of the utility model optical lens;
Fig. 2 is scheme two schematic diagram of the utility model optical lens;
Fig. 3 is scheme three schematic diagram of the utility model optical lens;
Fig. 4 is scheme four schematic diagram of the utility model optical lens.
[embodiment]
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated:
Scheme one:
This programme is for focusing eyeglass is at front end, i.e. one end of close shot object, towards one end of object space, as shown in Figure 1, focusing lens set 1 is a slice eyeglass, and fixing len group 2 is multi-disc eyeglass, in the time taking remote scenery, fixing len group 2 does not move, and focusing eyeglass, to moving near fixing len group 2 directions, reaches imaging clearly.Otherwise in the time taking closely scene, focusing eyeglass, to moving away from the direction of fixing len group 2, reaches imaging clearly.
Scheme two:
This programme is for focusing eyeglass is at front end, i.e. one end of close shot object, towards one end of object space, as shown in Figure 2, focusing lens set 1 is multiple eyeglass compositions, and fixing len group 2 is multi-disc eyeglass, in the time taking remote scenery, fixing len group 2 does not move, and focusing lens set 1, to moving near fixing len group 2 directions, reaches imaging clearly.Otherwise in the time taking closely scene, focusing lens set, to moving away from the direction of fixing len group, reaches imaging clearly.
Scheme three:
This programme is for focusing lens set is in rear end, i.e. one end of close imaging surface, towards one end of image space, as shown in Figure 3, focusing lens set 1 is a slice eyeglass, and fixing len group 2 is multi-disc eyeglass, in the time taking remote scenery, fixing len group does not move, and focusing eyeglass, to close fixing len prescription to movement, reaches imaging clearly; Otherwise in the time taking closely scene, focusing eyeglass, to moving away from the direction of fixing len group, reaches imaging clearly.
Scheme four:
This programme is for focusing lens set is in rear end, i.e. one end of close imaging surface, towards one end of image space, as shown in Figure 4, focusing lens set is multiple eyeglass compositions, and fixing len group 2 is multi-disc eyeglass, in the time taking remote scenery, fixing len group does not move, and focusing lens set, to close fixing len prescription to movement, reaches imaging clearly; Otherwise in the time taking closely scene, focusing lens set, to moving away from the direction of fixing len group, reaches imaging clearly.
Certainly, the scheme that can implement, focusing lens set also can be arranged on the middle optional position of lens wearer group.
In this optical lens, before imaging surface 3, be provided with optical filter 4 towards the one side of object space, as Figure 1-4.Described focusing lens set 1 and the lens of fixing len group 2 are sphere or are non-spherical lens.
This optical focusing system has solved the existing small-sized shortcoming and defect that focuses pick-up lens automatic focusing optical system, and it is short that it has focussing distance, can realize quick high definition and accurately focus, and overall volume is little, practical.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These Description of Knowledges are in order to explain principle of the present utility model, and can not be interpreted as by any way protection domain restriction of the present utility model.
