Abstract
Embodiments of the present invention provide a prism film and a method and an apparatus for manufacturing the prism film. The prism film comprises a substrate which is provided with prism protrusions formed of photoresist; wherein at least two prism protrusions have different heights. The embodiments of the present invention adopt the laser interference lithography apparatus for forming the prism film, such that the prism film has adjustable prism period and modulation depths. Moreover, the depth of modulation is distributed randomly on the surface of the manufactured prism film, and a prism direction and a prism period can be adjusted conveniently.
