A design of vehical wide-angle lens
ABSTRACT With the development of economy and the popularity of cars,vehical lens have been widely used in cars£¬including car parking system£¬road wayfinding system,pnorama system,tachograph and so on.The design of vehical lens attracks more attention and the demand increased year by year.The paper introduces how to use software CODEV to design an Vehical lens combining the non-spherical principles.The F-number is 2.8,FOV angle is 200¡ã,the effective focal length and the back focal length are 0.973 mm and 2.048 mm,and the length of the total lens group of the optical system is 11.44 mm.The illuminance of image with the height of 1.7 mm should not be less than 40% and the system has the structure of 1G3P, that it consists of a glass and three plastic lens.
