Web2.2 Off-axis generalized aspheric and conic mi rrors for ozone mapping satellite instrument Examples of mirrors for imaging systems on satellites have typically had surface slope errors called out in units of microradians. A typical exampl e is Surface slope errors sha ll be less than or equal to 50 microradians over the entire clear aperture. WebManaging Holography Errors in Asphere Metrology. Computer-generated holography is a quick method for measuring aspheres in a production environment. But care is required to minimize errors. Aspheric lenses are preferred over conventional spherical lenses in many optical systems for their high optical performance and lightweight and compact form ...

Instead, it has an aspheric surface (i.e. non-spherical), usually with counter-curves near its edges. These counter-curves direct light rays hitting the edges of a lens to converge at the same point of focus as the light rays hitting the center.
