All the lenses from the first lens to the sixth lens are prepared by optical glass; lens faces are all of spherical shapes. The utility model overcomes deficiency of prior arts and provides an economic optical system with high definition resolution and capable of being used day and night.
Description
[technical field]
The utility model relates to a kind of optical system, relate in particular to a kind ofly be applied to monitor, shooting, vehicle-mounted day and night share, high definition resolution, Eco-power optical system.
[background technology]
At present monitoring, shooting, the vehicle-mounted such shortcoming of large, medium visual field camera lens ubiquity: resolution is low, cost is expensive; And can only be in the situation that light be stronger uses.
Monitoring, shooting, the on-vehicle lens of main flow mainly is that resolution is lower on the market now, in a little less than light particularly night cisco unity malfunction, captured image is that whole sharpness or the acutance of picture is all not ideal enough, can not satisfy the high-resolution of picture of monitoring, shooting, vehicle-mounted requirement and the requirement that all worked in 24 hours far away.
The camera lens that overcomes above whole shortcomings is also seldom arranged now, so present large, the medium visual field camera lens of popular monitoring on the market, shooting, vehicle mounted, or resolution is lower, or cost is more expensive, or can only be in the situation that illumination is stronger uses.This has very large inconvenience in the use, can not satisfy the consumer convenient observe, inexpensive, day and night the needs such as share.
[utility model content]
The utility model has overcome the deficiencies in the prior art, provides a kind of and day and night shares, high definition resolution, Eco-power optical system.
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposal:
A kind ofly day and night share, high definition resolution, Eco-power optical system, it is characterized in that: include and be provided with successively from the object side to the image side first lens 1, the second lens 2, the 3rd lens 3, the 4th lens 4, the five lens, 5, the six lens 6 and image planes 7, the lensed material of described first lens 1 to the 6th lens 6 is optical glass, and the lens face type is spherical.
Aforesaidly a kind ofly day and night share, high definition resolution, Eco-power optical system, it is characterized in that being provided with optical filter 9 being provided with between the 3rd lens and the 4th lens between diaphragm 8, the six lens and the image planes.
Aforesaidly a kind ofly day and night share, high definition resolution, Eco-power optical system, it is characterized in that described the 4th lens and the 5th lens form balsaming lens.
Aforesaidly a kind ofly day and night share, high definition resolution, Eco-power optical system, it is characterized in that: the shape of described first lens is curved month type, the concave surface of these lens is towards diaphragm, its focal length is for just; The shape of the second lens is curved month type, and the concave surface of these lens is towards diaphragm, and its focal length is for negative; The 3rd lens are lenticular lens, and its focal length is for just; The 4th lens are the double concave type lens, and its focal length is for negative; The 5th lens are lenticular lens, and its focal length is for just; The 6th lens are lenticular lens, and its focal length is for just.
Aforesaidly a kind ofly day and night share, high definition resolution, Eco-power optical system, it is characterized in that this optical system adopts the forward and backward symmetric form of respectively establishing three sheet glass lens at diaphragm 8.
The utility model compared with prior art has advantages of as follows:
1, optical lens of the present utility model is comprised of 6 sheet glass lens, and the glass cost is more cheap; And the cost that has similar complete product camera lens now is generally more expensive.
2, camera lens of the present utility model can reach day and night the effect that shares, though also can in infrared light, become in the weak situation of light at night clearly as; Existing large, medium visual field camera lens generally can only be in the situation that illumination be stronger uses.
3, camera lens of the present utility model is a high definition camera lens, and resolution reaches 2,000,000 pixels, and edge resolution is high, can both become sharply defined image on whole image planes; Generally below 1,300,000 pixels, edge resolution is low for existing large, medium visual field resolution of lens.
4, illumination image planes of the present utility model are whole evenly, bright, and peripheral illumination is more than 60%; And existing large, medium visual field camera lens generally all is that the center is bright, and dark all around, peripheral illumination is generally about 40%.
5, color of the present utility model is clearly demarcated, and color reducibility and image planes are Well-recovered;
Will be under visible light and the infrared light before 6, the utility model has also solved independent blur-free imagings and cause the problem that the lens cost is relatively high and tolerance tight, yield is lower all.
[description of drawings]
Accompanying drawing 1 is optical system schematic diagram of the present utility model;
Accompanying drawing 2 is spot point range figures of the present utility model;
Accompanying drawing 3 is visible light MTF figure of the present utility model;
Accompanying drawing 4 is infrared light MTF figure of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind ofly day and night share, high definition resolution, Eco-power optical system, can be used for the sensor devices such as CMOS sensitive film or ccd chip, include and be provided with successively from the object side to the image side first lens 1, the second lens 2, the three lens 3, the four lens 4, the 5th lens 5, the six lens 6 and image planes 7.The lensed material of described first lens 1 to the 6th lens 6 is optical glass, and the lens face type is spherical, and cost can be lower like this, handling ease.
The shape of described first lens is curved month type, and the concave surface of these lens has the ability that changes big or middle field of view edge light refraction angle towards diaphragm.The shape of the second lens is curved month type, and the concave surface of these lens is towards diaphragm, and the curvature that these lens are second is larger, can also effectively reduce spherical aberration when further changing the deflection of light angle.The 3rd lens are lenticular lens.The second lens and the 3rd lens adopt positive and negative opposite lens, the aberration of the system that effectively reduces.The 4th lens are the double concave type lens.The 5th lens are lenticular lens.At the forward and backward symmetric form of respectively establishing three sheet glass lens of diaphragm 8, the symmetrical loose ability of system tolerance that guarantees before and after having.The 4th lens and the 5th lens combination are synthesized balsaming lens, thereby have effectively solved near the lens core shift sensitive issue of diaphragm.The 6th lens are lenticular lens, have the ability that guarantees the aberration equilibrium.For realizing best image planes effect, the rear portion of this optical system has also added optical filter, to filter out veiling glare, has good color reducibility when making image color beautiful and sharp keen.
In this optical system, the first lens focal length for just, second focal length of lens for negative, the 3rd focal length of lens for just, the 4th focal length of lens for bear, the 5th focal length of lens for just, the 6th focal length of lens is being for just, thereby so that the picture side of optical system main face forward shift, thereby so that system length shortening.Because the utility model optical system in the situation that considered respectively in the design in visible light and separately imaging of infrared light, has solved this class camera lens rare of day and night on the market.Because the utility model adopts the cleverly combination between eyeglass, its resolution can reach more than 2,000,000 pixels.In addition, the employed material of the utility model is all more cheap, and tolerance is loose, can realize producing in enormous quantities, thereby reduce cost this product is come into the market widely.
