Optical designers typically use aberration diagrams based on ray tracing to analyze the chromatic aberration performance of their optical system. However to evaluate the impact of chromatic aberrations on color fringes in images optical imaging simulations are necessary including the effect of spectral response of the sensor or film, exposure time, Gamma corrections, etc. We have analyzed the correspondence of classical chromatic aberration measures versus analysis based on image simulations. We propose a metric directly linked to color fringes in images which can be used to constrain and specify the chromatic aberration performance of an optical system.
Today's high performance cine lenses rely more and more on the use of aspheres. These are as powerful in correcting
aberrations as they are expensive if it is not possible to use
high-volume manufacturing processes. One possible solution
to meet the increasing demands of design to cost is the use of identical parts in several lenses. The biggest gain is
possible with the most expensive parts: the aspheres. In this presentation a successful as well as an ineffective way of
incorporating the same asphere in three lenses which differ by a factor of 1.5 in focal length will be shown.
In our digital age, digital cinematography is gaining importance. Therefore the camera lens division of Carl Zeiss decided to extend its conventional cine lenses with a set of digital prime lenses, the DigiPrimes. These lenses are designed for High Definition Television (HDTV) cameras with three 2/3-inch format CCD-Chips and a beamsplitter HDTV prism. There are six lenses with an effective focal length from 5mm to 40mm. The lenses have a telecentric design on the image side, because of the color separating prism. We will discuss some aspects of the mechanical and optical design and their influence on each other.
A new series of high performance lenses developed by Carl Zeiss for ARRIFLEX 35 mm cine cameras are described. Some aspects of selected lenses are discussed.
