A barcode imaging lens is designed with focus length 7.9 mm and field of view 52°. The image is received by a liner CMOS sensor. In order to obtain a low cost meanwhile a good imaging performance, plastic aspherical surface is used with high index factors to become a one glass one plastic lenses optical system (1G1P). Compared with traditional three glass lenses optical system (3G), 1G1P system design is of better imaging performance to meet the specification and only needs 50% producing cost of 3G. It has a potential market.
