Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
Denoting an optical system that involves both the reflecting and refracting of light, in order to reduce aberration.
- ‘Despite some improvements in narrowing the laser bandwidth, the lack of a glass material in addition to CaF 2 to compensate for chromatic aberrations makes a catadioptric design the only possible choice for the projection optics.’
- ‘One alternative for 126 nm is to eliminate refractive or catadioptric designs and instead use an all-reflective approach.’
- ‘More recently, it often shows up in fairly complex catadioptric systems as a simple, inexpensive substitute for an aspheric mirror.’
- ‘Most 157-nm lithography system designs are catadioptric, i.e., incorporating both mirrors and lenses in the optics to minimize the chromatic aberrations.’
