aplanat मीनिंग इन हिंदी

उदाहरण वाक्य

1. The Landscape, the Portrait, the Globe, and the Rapid-Rectilinear / Aplanat constituted the nineteenth-century photographer's entire lens arsenal.
2. However, symmetrical optical formulae such as the Rapid-Rectilinear / Aplanat and the Double Gauss are usually considered pleasing, while asymmetric retrofocus wide angle and telephoto lenses are often thought harsh.
3. The Rapid-Rectilinear and Aplanat lenses were scalable over many focal lengths and fields of view for all contemporaneous media, and they were the standard moderate-aperture, general-purpose lenses for more than half a century.
4. By coincidence, John Dallmeyer's Rapid-Rectilinear and Adolph Steinheil's Aplanat had virtually identical symmetric four-element formulae, arrived at almost simultaneously in 1866, all of which corrected most optical aberrations, except for spherical and field curvature, to f / 8.
