A novel ultraviolet detection lens relates to the technical field of manufacturing camera lenses for ultraviolet detection, and is characterized in that it is composed of an optical lens made of a single quartz glass, and the front diverging lens and the diaphragm are composed of a single negative lens and three single A lens group composed of positive lenses, behind the stop is a single positive lens. The structure can reduce the inclination angle of the oblique beam inside the system, and the whole system can correct the aberration of the large field of view; the relative aperture of the lens increases to 1/3; the aperture of the entire optical system is reduced, and the weight is reduced; High efficiency and good energy utilization can ensure that the field of view of the entire detection system reaches 112 degrees.
Description
The utility model is that a kind of new ultra-violet is surveyed camera lens, relates to the manufacturing technology field of ultraviolet detection with camera lens.
The ultraviolet detection camera lens is because the wavelength that uses is short, and the glass material kind of design usefulness is limited, proofreaies and correct relatively difficulty of aberration, thereby the ultraviolet detection lens construction of big visual field object lens of large relative aperture more complicated all, eyeglass quantity is many, and its result directly causes lens transmission efficiency low, and capacity usage ratio is poor.
The purpose of this utility model can reach by following measure: the optical lens that the ultraviolet detection camera lens adopts single silica glass material to make constitutes, after the lens combination of being made up of negative lens and positive lens between preceding divergent lens and light hurdle, light hurdle is the monolithic positive lens.
The purpose of this utility model can also reach by following measure: the lens combination between preceding divergent lens and the light hurdle is made up of monolithic negative lens and three monolithic positive lenss.
Description of drawings:
Fig. 1 is an optical structure chart of the present utility model
Fig. 2 is an encircled energy curve map of the present utility model
The utility model is described further below in conjunction with the embodiment accompanying drawing:
As shown in Figure 1: six optical lenses that ultraviolet detection camera lens adopting quartz glass is made constitute.The lens combination of being made up of a monolithic negative lens (2) and three monolithic positive lenss (2), (3), (4) between divergent lens (1) and light hurdle (6) before the quartz glass, light hurdle (6) are monolithic positive lens (7) afterwards.
The utility model is compared prior art and is had following advantage:
This structure can guarantee that the visual field of whole detection system reaches 112 degree, and guarantee that the skew ray bundle of big visual field passes through: preceding divergent lens (1) and negative lens (2) can reduce the pitch angle of internal system skew ray bundle, make total system can proofread and correct the aberration of big visual field; The lens combination that positive lens (3), (4), (5) constitute can make the relative aperture of camera lens increase, and reaches 1/3.Light hurdle (6) places between lens (5) and the lens (7), is positioned at the rear portion of total system, makes the whole optical system bore reduce weight saving.Whole optical system all adopts simple lens, has both avoided lens to glue together this complicated step, has also avoided because the influence of the error object matter of gummed.The transmitance height of this camera lens, the availability height (as shown in Figure 2) of energy.
Claims (2)
1, the ultraviolet detection camera lens is made up of optical lens, the Guang Lan both sides are respectively arranged with negative lens or positive lens along optical axis, it is characterized in that: the optical lens that adopts single quartz glass to make constitutes, the lens combination of being made up of negative lens and positive lens between preceding divergent lens (1) and light hurdle (6), light hurdle (6) are monolithic positive lens (7) afterwards.
2, ultraviolet detection camera lens according to claim 1 is characterized in that the lens combination between preceding divergent lens (1) and light hurdle (6) is made up of monolithic negative lens (2) and three monolithic positive lenss (3), (4), (5).
