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).

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. |

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. More historical information about: |
