Paper Abstract

Two different optical testing methods which used to test aspheric surface are introduced in this paper. An aspheric surface of Φ340mm F/1.3 is tested with help of Computer-generated hologram (CGH) or Null compensator, and then these two testing results are compared. Matched result proves that these methods are believable and reliable. This compare testing method can be introduced to test similar aspheric surface.
