Optical imaging

The lens of a camera ultimately determines the true quality of a photograph. It is compa-rable to the human eye. What you see is the projected image from your eye to your retina. This image is finally interpreted by your brain. In digital photography, the image is projected by the Variogon lens (the camera's eye) to the Color Science Chip (the camera's retina). From this electronic sensor it is delivered to the intelligent software algorithms (the camera's brain). Kodak, well known for its intensive research and development of imaging technologies, is leading the way with its Color Science Chip. In conjunction with the Color Science Chip, the Variogon lens delivers fascinating, brilliant color prints, delighting
the most astute photographer.

Lens performance

 

The high-precision Variogon lens is the result of very complicated optical computations and consists of many movable single precision lenses. As per optical laws, all single lenses work precisely together to achieve the highest requirements of modern digital cameras.

Variogon lenses deliver vivid color and sharp details in most lighting conditions, from dimly lit interiors to sunlit exteriors. With all our lenses, from wide-angle to true telephoto, you'll witness striking edge-to-edge brightness and sharpness.

Variogon lenses consist of aspheric elements to produce a compact lens that can go virtually anywhere to capture stunning photos. These aspheric elements prevent distortions and the loss of edge sharpness that can be created by spherical lenses.

In high zoom Kodak Easyshare digital cameras, extra
low dispersion glass elements are utilized to reduce chromatic aberrations that are difficult to control in high-ratio zoom lenses. The result is reduced  flare, enhanced contrast and sharpness, and saturated colors in all zoom ranges.
 

Optical design
Optical design by itself is a very difficult skill, especially the optical correction of a zoom lens system. A zoom lens is made of several single lenses, which must work together in conformity with optical relationships to get a sharp image over the entire zoom and focusing range, as well as over the complete image area. To achieve this aim, it is absolutely essential to minimize the physically determined optical aberrations like spherical aberration, coma, field curvature, astigmatism, distortion, as well as chromatic aberration.
