Description
Technical field
The invention belongs to lens technology field, particularly relate to a kind of high definition ultra-wide angle tight shot.
Background technology
2.8mm camera lens is widely used in the occasion needing the large visual field to monitor, and market demand is very big.Traditional 2.8mm camera lens is generally full glass mirror, due to field angle very large (usual maximum field of view angle can reach more than 140 °), causes its edge picture element to be difficult to be guaranteed.
The 2.8mm of current high definition possesses the glass mirror of more than 6 pieces usually, and visible ray resolution is more than 2,000,000, and infrared resolution rate is more than 1,000,000.Along with the requirement of development people to sharpness of technology is more and more higher, the chip of 4,000,000, five mega pixels emerges in an endless stream, and therefore needs a resolution can reach the 2.8mm camera lens of five mega pixels.If by traditional thinking, generally have two kinds of ways to improve resolution: one is adopt less eyeglass to reduce clear aperature, and two is adopt more eyeglass.
Adopt more eyeglass no doubt can promote the performance of camera lens, but the thing followed is the increase of cost.Cost can be made to reduce although clear aperature is reduced in employing, lens imaging Quality Down can be caused.When adopting full glass mirror to design as can be seen here, visible ray and infrared light confocal imaging camera lens directly cannot average out on Cost And Performance.
And for 2.8mm tight shot, still need and will solve following technical barrier:
The first, visible ray is identical with infrared light focal length.
Monitoring camera is all in running order with night by day, the mainly natural light of the illumination employing on daytime, therefore the light mainly visible ray that daytime, object sent, then need night to use infrared light floor light, the light that therefore night, object sent is infrared light or the mixing light that is made up of infrared light and visible ray mainly.And due to visible ray (wavelength is for 550nm) and the refractive index of infrared light (wavelength is for 850nm) in same optical glass, optics plastic cement different, this often causes the focal position of the focal position of visible ray and infrared light different, that is by visual light imaging after lens imaging clearly position and near infrared imaging position is different clearly.The common monitoring camera which results on the market is difficult to take into account the imaging clearly of day and night.
The second, when variation of ambient temperature time, camera lens does not need again to focus and just can ensure imaging clearly.
Monitoring camera is widely used in indoor, outdoor, and 1 year 365 day 24 hours every day is in running order, and the variation of ambient temperature residing for camera lens is huge.The typical operating temperature requirements of monitoring camera is-30 DEG C ~ 80 DEG C, and camera lens must ensure that imaging is still equally clear with 20 DEG C (normal temperature) in the scope that this temperature difference reaches more than 120 degree Celsius, when again not focusing.
Change due to the refractive index meeting temperature influence of eyeglass material, lens dimension, lens barrel material, microscope base material can be expanded with heat and contract with cold along with the change of temperature, these factors cause common monitoring camera under high and low temperature environment, there will be burnt (rear cut-off distance) after different imagings, are called the temperature drift of lens imaging.
In view of this, necessaryly provide a kind of high definition ultra-wide angle tight shot, it can realize large aperture (F1.8) by reasonable combination glass lens and plastic lens, image quality is good, visible ray resolution can reach five mega pixels, and makes infraredly under the prerequisite again do not focused on, also can reach four mega pixels, even if also can realize clear bright monitored picture at night under low-light (level), there is temperature compensation function simultaneously, use under the environment of-30 DEG C ~ 80 DEG C and also can not run Jiao.
