Above-mentioned positive crescent moon lens A-4 is made by FK61 Extra-low Dispersion material.
Above-mentioned color filter film comprises near infrared 6, yellow 8 and 2 three kinds of visible lights, these three kinds of color filter films are uniformly distributed along the circumference and are installed on the rotating disk 3 of microscope base 10 rear ends, described rotating disk 3 outer radial periphery sides are provided with the Hall element 5,9,7 of corresponding three kinds of color filter films 6,8,2, also be provided with the magnet steel 4 that triggers Hall element on the described rotating disk 3, described rotating disk 3 outer radial periphery portions are provided with driving cog 3-1, and the driving gear 1 that the motor 11 of described driving cog 3-1 through being laid in microscope base 10 belows drives drives.
The wavelength that above-mentioned near infrared color filter film uses is 750～950nm, and described yellow color filter film uses the yellow color filter film of CB6.
The optical system that is made of above-mentioned lens set has reached following optical index:
Focal length: f ' min=20mm; F ' max=500mm(becomes 25 times of multiple proportions);
Relative aperture D/f '=1/2.8-1/7.5;
Field angle 2w=22.6 °-0.45 °;
Optical texture length: Σ L≤261mm;
Become times stroke≤70mm;
Resolution of lens: adaptive with super mega pixel ccd video camera or cmos video camera;
The Penetrating Fog optical filter see through spectrum: 750～950nm;
When optical design, in preceding fixing len group, increase a constituent element (positive crescent moon lens A-4), and select the ED(Extra-low Dispersion for use) optical material, improved the focal power ability to take the burden of the highest preceding fixedly group of light height like this, aberrations such as optical lens second order spectrum have been reduced effectively, the resolution of camera lens is significantly improved, reach mega pixel, can be adaptive with the video camera of high definition.
The haze weather conditions such as rain, snow, mist of considering are descended, and contain small water particle in air, according to Mie theory: when the ratio C/λ of scattering particle radius C and incident ray wavelength X hour, descend less at the luminous energy of image planes epigraph.When optical design, strengthened the weight of near infrared spectral line (the above spectral line of wavelength X 800nm) in view of the above, made camera lens higher resolution be arranged at near-infrared band.And to carry out film be optimal design, optical lens is had in the 450nm-950nm wavelength band be higher than 80% transmitance, in light path, placed simultaneously high-precision color filter film throw-over gear, by the throw-over gear of micromotor drive controlling color filter film, high-pass filtering by color filter film, filter out the visible light of 450～700nm, the above light ray anti-reflection of 750～950nm being reached filter out can not be by the visible light of mist, improve the ratio of near infrared spectrum, thereby increase the detectivity of distant object.
Above-mentioned color filter film is implemented structure such as Fig. 2, shown in Figure 3, the motion of electric machine assembly driven by motor motor driving gear, and the motor driving gear drives the rotating disk motion that drives color filter film by driving cog.Because the rotating disk motion makes the also motion of being located on the rotating disk simultaneously of magnet steel, when magnet steel respectively when the Hall element, Hall element is under the action of a magnetic field, become low resistive state by high-impedance state, Hall component output becomes low level by high level, this signal is passed to microcomputer on the camera lens control panel, and after computing machine obtained the signal of Hall element, the order motor stopped; Then rotating disk stop motion, design the relative position of color filter film, Hall element, magnet steel, can make color filter film accurately be parked on the optical axis position, three kinds of color filter films of the utility model setting are respectively: visible light, 750～950nm near infrared, the yellow color filter film of CB6, give computing machine by three hall element output signals respectively, computing machine just can be parked in our needed color filter film position in the middle of the light path accurately according to host command and Hall element signal.Its control principle block diagram as shown in Figure 4.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
