aspheric surface मीनिंग इन हिंदी

उदाहरण वाक्य

1. Unlike conventional optical grinding, complex aspheric surfaces can be machined easily.
2. It was reported by Otto Ahlstr�m in 1950 that most have aspheric surfaces.
3. This leads to strong divergences when it comes to fitting the equation to an aspheric surface.
4. In recent years, computer-generated holograms ( CGHs ) have begun to supplement null correctors in test setups for complex aspheric surfaces.
5. Aspheric surfaces can also be made by polishing with a small tool with a compliant surface that conforms to the optic, although precise control of the surface form and quality is difficult, and the results may change as the tool wears.
6. The 400 DO lens had a multilayer diffractive element containing concentric circular diffraction gratings to take advantage of diffraction's opposite color dispersion ( compared to refraction ) to correct chromatic and spherical aberrations with less low dispersion glass, fewer aspheric surfaces and less bulk.
7. The development of the'Tessar'lens is discussed by Nasse, and shows its transformation from an f / 6.3 lens for plate cameras using the original three-group configuration through to an f / 2.8 5.2 mm four-element optic with eight extremely aspheric surfaces, economically manufacturable because of its small size.
