| titleOfInvention | The method for designing of infrared imaging camera lens and refrigeration mode infrared imaging camera lens of no focusing |
| abstract | The invention discloses a kind of method for designing of infrared imaging camera lens and refrigeration mode infrared imaging camera lens of no focusing, wherein, the method includes：According to lens focus f, the relative aperture F and primary standard substance relativeness setting N group lens between L, so that incident illumination is adjusted by N group lens, wherein, N >=3, and all using different infrared optical materials between every group of lens, need between the lens group of different infrared optical materials to meet following condition：Total focal power that is focal power and being equal to camera lens of different materials lens group；The focal power of different materials and heat differential coefficient product and be equal to zero；The focal power of different materials and the ratio of Abbe number and be equal to zero；By refrigeration type infrared detector, the incident illumination after adjusting is imaged.By using the present invention, the corresponding depth of field can cover all positions in investigative range, can make target blur-free imaging, solve the problems, such as prior art. |
