They can also be reduced dramatically by using an aspheric element, but these are more complex to grind than spherical or cylindrical lenses.

Philips solved a significant problem with electronic displays in the mid-1990s by slanting the cylindrical lenses with respect to the underlying pixel grid.
13.
Deep Space 1 has a new kind of solar power array that uses 720 cylindrical lenses to concentrate sunlight onto 3, 600 electricity-producing cells.
14.
;Cylindrical : A cylindrical Fresnel lens is equivalent to a simple cylindrical lens, using straight segments with circular cross-section, focusing light on a single line.
15.
On a lenticular sheet, each cylindrical lens refracts the different pictures to different eyes without the need for the viewer to look into a device.
16.
This type produces a sharp image, although not quite as clear as the equivalent simple cylindrical lens due to diffraction at the edges of the ridges.
17.
The strips were later replaced by Hess with an array of cylindrical lenses known as a lenticular screen, to make more efficient use of the illumination.
18.
Airy produced lenses to correct his vision problems by 1825, while other sources put this into 1827 when Airy obtained cylindrical lenses from an optitian from Ipswich.
19.
After the SHG crystal, a set of cylindrical lenses is used to image the signal onto a camera with wavelength mapped vertically while delay is mapped horizontally.
20.
These ribbed sheets are called lenses, or lenticular sheets, because they are actually dozens of optical-grade cylindrical lenses sitting in parallel lines on top of several specially prepared images.
