ABSTRACT:
The present invention provides a hybrid lens having an axially asymmetrical non-spherical shape, good mass productivity, and excellent shape precision surface precision as well as environment resistant property, and a method for fabricating same, as well as a method and a device for a laser printer using that hybrid lens. In particular, there are disclosed a method, by which, when an axially asymmetrical non-spherical convex lens is formed by the replica method, the shape thereof is transcribed with a high precision, as well as a method and a device for fabricating an axially asymmetrical non-spherical concave lens (female die) serving as an original for the transcription. In a device for fabricating a female die by direct grinding, the positions of a rotation axis of an object to be worked and a rotation axis of a grinding wheel are controlled and it has further a function of correcting mounting errors, when the object to be worked and the grinding wheel are mounted.
