Exempel på hur man kan använda ASPHERICAL i en mening

• Many EF lenses include such features as Canon's ultrasonic motor (USM) drive, an image stabilization system (IS), diffractive optics (DO) and, particularly for L-series lenses, fluorite and aspherical lens elements.
• The invited papers were by Frank Twyman (of Hilger and Watts) on the production of aspherical surfaces; Louis de Broglie on image formation, Jean Cabannes on the development of optics in France, and Pierre Fleury reviewed the history of the Institut d'Optique and research pursued since 1940.
• They are also used in combination with reflective elements (catadioptric systems) such as the aspherical Schmidt corrector plate used in the Schmidt cameras and the Schmidt–Cassegrain telescopes.
• His research, concentrating on optical spectroscopy, showed that many core-collapse supernovae result from massive stars with partially or highly stripped envelopes, helped establish the Type IIn subclass characterized by ejecta interacting with circumstellar gas, observationally identified the progenitors of some supernovae, revealed that many supernovae are quite aspherical, and showed that Type Ia supernovae exhibit considerable heterogeneity—crucial to the development of methods to calibrate them for accurate distance determinations.
• If one works with CW complexes, one can reformulate this condition: an aspherical CW complex is a CW complex whose universal cover is contractible.
• More generally, the fundamental group of a closed, connected, orientable aspherical manifold of dimension n has cohomological dimension n.
• Precision gobs can be used as preforms for the production of aspherical lenses in a precision molding process.
• The optical construction of the lens contains 15 lens elements, including two aspherical lens elements, one SLD (Special Low Dispersion) element, and one ELD (Extraordinary Low Dispersion) element.
• It integrates a high amount of technologies: 21 elements in 14 groups including 1 High Refractive Index (HRI), 3 Extra-low Dispersion (ED) and 2 aspherical lenses, Super Integrated Coating (SIC), internal focusing (IF) with world's fastest quiet ultra-fast Voice Coil motor (VCM), silent 3-speed PD-Zoom, Vibration Reduction (VR II), retractable lens mechanism and 7 rounded diaphragm blades.
• In 1994 Braat won the Edward Longstreth Medal for Computer and Cognitive Science of the Franklin Institute for "contributions to optical data recording and design of aspherical objective lenses for read-out systems of optical storage".
