lens formula मीनिंग इन हिंदी

उदाहरण वाक्य

1. Adjust the spacing according to the lens formula or empirically.
2. Among his results, Gauss showed that under a paraxial approximation an optical system can be characterized by its cardinal points and he derived the Gaussian lens formula.
3. The distances u2 and v2 along the line of sight are " not " the object and image distances u and v used in the thin-lens formula
4. These advantages stem from having fewer moving parts, optical elements optimized for one particular focal length, and a less complicated lens formula which means that they suffer from fewer problems of optical aberration.
5. The Double Gauss was likely the most intensively studied lens formula of the twentieth century, producing dozens of major variants, scores of minor variants, hundreds of marketed lenses and tens of millions of unit sales.
6. They may be made of one or more conventional lenses or achromatic doublets, or a long cylindrical thin lens formula with object distance s = 2f, the image distance is calculated to s'= 2f ).
7. In converting the measurements obtained from the corneal surface into a dioptric value, the B & L keratometer uses the general lens formula ( n-n ) / R and assumes an n of 1.3375 ( compared to the actual corneal refractive index of n = 1.376 ).
8. If the distances from the object to the lens and from the lens to the image are " S " 1 and " S " 2 respectively, for a lens of negligible thickness, in air, the distances are related by the "'thin lens formula " ':
9. Although the Portrait was the first mathematically computed lens formula, trial and error would continue to dominate photographic lens design for another half century, despite well-established physical mathematics dating from 1856 ( by Ludwig von Seidel [ modern Germany ], working for Hugo Adolph Steinheil [ modern Germany ] ), to the detriment of lens improvement.
