Decenter optics
WebDespace induces only spherical aberration (widening the gap undercorrection, and vice versa). Tilt and decenter will induce all-field coma, but will also affect lateral color error (larger tilt/decenter values will also induce image tilt, but they are not possible in …

WebDiameter tolerance is a critical mechanical tolerance that must be considered when mounting an optic. Deviations from the nominal diameter may prevent lenses from seating properly in their mounting fixture, … WebLenses with nearly concentric radii are difficult to center since a large amount of material must be removed to correct for surface-to-surface relative decentering. To ensure that a lens can be centered, concentricity …
WebAug 5, 2013 · Over a billion mobile phone camera lenses are produced each year. Small improvements in production yields have the potential to reap significant cost savings! The starting system is a 4.53 mm, ƒ/2.8 lens with a 66⁰ full field of view. It consists of four elements in which every surface is a 12 th to 14 th order asphere, and a cover plate.
