lens combination meaning in Hindi

Examples

1. The optics consist of a spherical lens and cylindrical lens combination.
2. The main task of this lens combination is the deceleration of the fast 20 keV electrons to energies for which the channelplate has its highest sensitivity.
3. In photography and videography, a "'lens adapter "'is a device that enables the use of camera and lens combinations from otherwise incompatible systems.
4. When the successor GH2 camera was introduced, Panasonic offered as another option, a much less expensive ( and less capable ) 3x zoom 14-42mm kit lens, in addition to the 14-140mm 10x zoom lens combination.
5. He therefore set about to design and construct lenses of superior performance, combining lenses of crown and flint glasses of different dispersion, in order to cancel chromatic aberration, showing that spherical aberration could be minimised by the correct separation of the lens combinations, which led to the perfection of the optical microscope.
6. As early as 1915, the technological push by-such intellectual giants as A . H . Rudd of the Pennsylvania R . R . and his concept of speed signalling combined with his development of the Position Light signal and the concurrent color-light signals using William Churchill's doublet lens combination in practical terms made the semaphore technically obsolete.
7. Digital backs which are used in place of the normal film back are available for most medium and all large-format cameras with adaptors which can allow the same digital camera back to be used with several different cameras, allowing a photographer to choose a body / lens combination best suited for each application rather than using a body / lens system which represents a compromise of design to fit a variety of applications.
