Description

Big visual field folding, which spreads out, mixes day blind UV warming optical system
Technical field
Spread out the present invention relates to a kind of big visual field folding and mix day blind UV warming optical system, belong to UV warning technology neck Domain.
Background technology
Ultraviolet alarm system service band is the solar blind light spectrum area of air.Solar blind light spectrum area refers to that wavelength is 200~300nm Ultraviolet band, due to the absorption of ozone, the ultraviolet radioactive of this wave band is few in near-earth area content, so being accused in the wave band When alert, sky is dark background, and interference is weak, false alarm rate is low.
UV warning technology is to receive the day from monitoring objective after blind ultraviolet radioactive signal using optical system, is passed through Optical radiation signal is changed into electric signal and is sent to computer control platform by photo-translating system, computer control platform judge its with Setting suspicious radiation signal it is same or similar after, at once to automatic servo system send control signal, complete audible and visual alarm With automatic avoiding action.
In the prior art, with the immediate day blind UV warming optical system of the present invention by being published in 2013.9 publication 《Laser and optoelectronics are in progress》The text of one entitled " day blind UV warming Optical System Design " in (reel number 50.102203) Offer disclosed.The whole optical system of the program is only made up of 5 lens, including non-spherical element and binary diffraction element； Service band is 240~280nm；Compared to such scheme, visual field is significantly expanded to 40 ° by 30 °, and relative aperture slightly reduces, For 1:3.But compared to the ultraviolet detector that the current pixel dimension being easy to get is 13.5 μm of 13.5 μ m, the point of energy hot spot Row figure root mean square radii is much smaller than pixel dimension, causes to waste；In addition, the angle of visual field of the optical system is still less than normal.
The content of the invention
The purpose of the present invention is to maintain the blind UV warming optical system of the day containing non-spherical element and binary diffraction element Further expand visual field on the premise of the relative aperture of system is constant, therefore, we have invented a kind of big visual field folding mixing day of spreading out is blind UV warming optical system.
The big visual field folding of the present invention spreads out mixing day blind UV warming optical system characterized in that, as shown in figure 1, positive light focus Spend bent moon convex lens 1, the negative power biconcave lens 2 containing binary face, positive light coke biconvex lens 3, containing it is aspherical just Focal power biconvex lens 4 and sequentially coaxially arranged in the direction of propagation of light containing aspherical negative power biconcave lens 5, Diaphragm 6 is arranged on positive light coke biconvex lens 3, containing between aspherical positive light coke biconvex lens 4；Positive light coke bent moon is convex Lens 1, positive light coke biconvex lens 3 and the material containing aspherical positive light coke biconvex lens 4 are CaF2, contain binary The negative power biconcave lens 2 in face and material containing aspherical negative power biconcave lens 5 are F_SILICA (tekites English)；The face type and radius of curvature of 10 minute surfaces that the direction of propagation of 5 lens along light is arranged in order, at intervals of：Convex spherical 17.150328,3, concave spherical surface 28.529592,9.613923, concave spherical surface -23.445222,2.4672, recessed binary diffraction face 18.434021,2.186228, convex spherical 14.630195,5.9474, convex spherical -17.178268,0.662202+5.160182, Convex spherical 18.308229,11.014354, convex aspheric surface -6.969828,0.673681, recessed aspherical -7.264324,2.4, it is recessed Sphere 22.615489, listed data unit are mm；The service band of the optical system is 240~280nm, and the angle of visual field is 64 °, relative aperture 1:3.
According to the present invention big visual field folding spread out mixing day blind UV warming optical system structure, material and mirror types and Radius of curvature and interval, while simple in construction, object lens of large relative aperture effect is obtained, compared to 40 ° of visual fields of prior art, this Invention significantly expands visual field, reaches 64 °, and this can reduce the number of splicing when carrying out field stitching, reduce the loss of luminous energy. The present invention have also been introduced binary diffraction face and aspherical, and still, compared to prior art, the position of introducing and face number are different, this So that optical system expands visual field while object lens of large relative aperture is kept.According to point range figure, the different pictures in image planes 7 (IMA) The root mean square radii (RMS radius) of high point range (Spot Diagram) is up to 9.373 μm, with the μ of ultraviolet detector 13.5 The pixel dimension matching of m × 13.5 μm.
