Author Affiliations +
A novel car camera lenses have been designed. To reduce the cost, the system gives up the glued lenses. The whole optical system is made of six separated lenses and an IR-Cut Filter, among which there is two aspheric lenses and four spherical lenses. All lenses are made of glass. The resolutions of car camera system is three million pixels and the field angle is 150°.The Tangential MTF is 0.2 at spatial frequency of 300 cycles/mm when field angle is equal to 150°. The axis MTF is 0.7 at spatial frequency of 150 cycles/mm. The overall length of system is 18.23mm. The F-number is 2.8 and the effective focus length is 1.6mm. The new-designed car camera lenses can provide high-resolutions and very wide field angle. At the same time, the glass structure of lenses enjoys better thermal and mechanical stability than polymer lenses. The novel car-camera lenses will be then tested in the experiment.
