摘要：
This paper discusses the properties of the second-order aberrations that arise in centered optical systems that contain an aspheric surface formed by rotating any plane curve around the normal at some point of it if this normal is not the axis of symmetry of the curve. It is shown that the angular size of the slit field of a three-mirror objective without screening is increased by 10-26% when an aspheric surface of the second type (an oblate spheroid) is replaced in this system by a surface with the aspheric mentioned above.
