Apochromatic lenses are sometimes recommended due to their improved focusing across the spectrum.
2.
Graphic arts process ( copy ) cameras generally use apochromatic lenses for sharpest possible imagery as well.
3.
These are 6-element, 4-group apochromatic lenses with a 75?angle of coverage.
4.
Subsequently the new glasses would demonstrate their value in correcting astigmatism, and in the production of achromatic and apochromatic lenses.
5.
Of the 50 images, 48 will offer $ 40 payments, while two ( grape and apochromatic lens ) will pay out $ 15.
6.
This is a 6-element, 4-group apochromatic lens design, which has since been replaced by the Apo-Symmar L-Series.
7.
Normally, lens designs are optimized so that two or more ( at least three for apochromatic lenses ) wavelengths of light in the visible range focus at the same plane.
8.
The first apochromatic lens for consumer cameras was the "'Leitz APO-Telyt-R 180mm f / 3.4 "'( 1975, West Germany ) for Leicaflex series ( 1964, West Germany ) 35mm SLRs.
9.
When photographing subjects which must be very accurately represented, for example in making a mask for integrated circuit manufacture, apochromatic lenses of very high geometric accuracy and minimal color aberration ( traded off against a small maximum aperture ) and high price, are used.
