Webfit sphere. This provides a meaningful quantification of the testability of the surface. The RMS slope of this departure can be easily calculated, and is proportional to mean fringe … WebAs the two relations imply, Petzval radius is independent of object and image distance. For a single lens, Eq. 28.1 can be simplified to: R P = -nf (28.2) where n is the glass refractive and f the lens focal length. FIGURE …
One method to reduce this aberration is to insert an aperture stop (iris) in order to remove edge light rays. This method, however, greatly decreases the light collecting power of the lens. See more Petzval field curvature, named for Joseph Petzval, describes the optical aberration in which a flat object normal to the optical axis (or a non-flat object past the hyperfocal distance) cannot be brought properly into focus … See more • Field flattener lens See more Consider an "ideal" single-element lens system for which all planar wave fronts are focused to a point at distance f from the lens. Placing this … See more WebVideo created by Universidad de Colorado en Boulder for the course "Design of High-Performance Optical Systems".
