Described the first negative eyeglass group G1, the variable spaced of the second positive eyeglass group G2.
It is configured with diaphragm S between described the first negative eyeglass group G1, the second positive eyeglass group G2, determines F value size.Zoom
And during focus, relative imaging target surface I position is fixed.
The principle of the present invention is: during shooting, according to arrange CCD and CMOS(do not illustrate) etc. photoelectric sensor, at camera lens
The signal of telecommunication is converted optical signals on imaging target surface I.First negative eyeglass group G1 moves on optical axis according to it and carries out focus, correction
Due to the image speckles when camera distance of zoom and subject changes.Move on optical axis during second positive eyeglass group's G2 zoom
Dynamic.When telescope end zoom, the second positive eyeglass group G2 moves to object end from imaging end on optical axis.During focus, relative imaging
Target surface I fixes position.Second positive eyeglass group G2 by least use 2 aspherical lens, the sphere astigmat that can preferably make corrections and
Astigmatism.
When visible ray and the simultaneous situation of near infrared light occur, the second positive eyeglass group G2 and imaging target surface I it
Between insert optical filter F.Optical filter F may select the one of which through visible ray or near infrared light, it is achieved only with visual
Light, or only with the monitoring under near infrared light state.Optical filter F not only limits the use of a piece of, it is possible to prepare to select through visible ray
Optical filter and selection, through the optical filter 2 of near infrared light, carry out individually plugging off switching on optical axis.
Design science of the present invention is reasonable, has ultra-wide angle, heavy caliber, high-performance, zoom ratio 3～about 4 times, at visible ray
And the advantage that can monitor under near infrared light.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
With reference to Fig. 1, this detailed description of the invention by the following technical solutions: it comprise the first negative eyeglass group G1, diaphragm S, the
Two positive eyeglass group G2, optical filter F and imaging target surface I, be disposed with the first negative eyeglass from object end to the optical axis of imaging end
Group sets between G1, the second positive eyeglass group G2, optical filter F and imaging target surface I, and the first negative eyeglass group G1, the second positive eyeglass group G2
It is equipped with diaphragm S.
The first described negative eyeglass group G1 generally bears lens set, by convex surface facing object end negative meniscus lens one L1,
Concave-concave eyeglass L2, convex surface facing object end planoconvex lens L3 constitute, convex surface facing negative meniscus lens one L1, the convex surface of object end
Concave-concave eyeglass L2 it is provided with between the planoconvex lens L3 of object end.First negative eyeglass group G1 is mobile on optical axis to be closed
Burnt.If when shortest focal length is fW, longest focal length is fT, shortest focal length between the positive eyeglass group G2 of the first negative eyeglass group G1 and second
First negative eyeglass group G1 and second positive when being spaced apart DT of eyeglass group G2 when being divided into DW, longest focal length, meets below equation:
5.3 ＜ (DW-DT)/(fT/fW) ＜ 6.2 (1)
Formula 1 defines the 1st eyeglass group G1 and the ratio of the 2nd eyeglass group's G2 interval variation amount after zoom ratio and zoom.If
Meeting this condition, can preferably make corrections astigmat.If beyond higher limit, be conducive to the astigmat that makes corrections, but camera lens will be caused the most large-scale but also
Expensive.If less than lower limit, the strength of the most each group becomes strong, can increase the difficulty of astigmat correction.
The generally positive lens set of the positive eyeglass group G2 of described second, by biconvex eyeglass one L4, bearing convex surface facing object end
Meniscus two L5, biconvex eyeglass two L6, negative eyeglass L7 convex surface facing object end, biconvex eyeglass three L8, concave surface are towards object
The negative meniscus lens L9 of end sets gradually composition, convex surface facing negative meniscus lens two L5 and the biconvex eyeglass two L6 glue of object end
Conjunction, negative meniscus lens L7 and biconvex eyeglass three L8 are glued.Upper note the 2nd eyeglass group has convex lens sheet L6, sets note convex lens sheet L6 to d
When the Abbe number of line is vdL6, meet below equation:
VdL6 ＞ 80.0 (2)
Described the first negative eyeglass group G1, the variable spaced of the second positive eyeglass group G2.
It is configured with diaphragm S between described the first negative eyeglass group G1, the second positive eyeglass group G2, determines F value size.Zoom
And during focus, relative imaging target surface I position is fixed.
The principle of this detailed description of the invention is: during shooting, according to arrange CCD and CMOS(do not illustrate) etc. photoelectric sensing
Device, converts optical signals into the signal of telecommunication on lens imaging target surface I.First negative eyeglass group G1 moves on optical axis according to it and carries out
Focus, makes corrections due to the image speckles when camera distance of zoom and subject changes.During second positive eyeglass group's G2 zoom
Move on optical axis.When telescope end zoom, the second positive eyeglass group G2 moves to object end from imaging end on optical axis.During focus,
Imaging target surface I position relatively is fixed.Second positive eyeglass group G2 is by least using 2 aspherical lens, and can preferably make corrections ball
Face astigmat and astigmatism.
When visible ray and the simultaneous situation of near infrared light occur, the second positive eyeglass group G2 and imaging target surface I it
Between insert optical filter F.Optical filter F may select the one of which through visible ray or near infrared light, it is achieved only with visual
Light, or only with the monitoring under near infrared light state.Optical filter F not only limits the use of a piece of, it is possible to prepare to select through visible ray
Optical filter and selection, through the optical filter 2 of near infrared light, carry out individually plugging off switching on optical axis.
This detailed description of the invention design science is reasonable, have ultra-wide angle, heavy caliber, high-performance, zoom ratio 3～about 4 times,
The advantage that can monitor under visible ray and near infrared light.
