3.2.2 Optic Academy

3.2.3 CCD Optic Module

General Description

For a complete and working IVS, either the optic silent or the optic acacemy has to be installed inside the CCD optic module. They are easily interchangeable.

The optic academy forms an image on the CCD chip based on the 35mm academy format with a picture width of 22mm. To check for important objects outside the image recorded on film there is an additional area around the format markings.

The lenses are especially designed and built for the use with the ARRIFLEX 535B to achieve the best image quality possible. The aperture of 1:1.4 is particularly important for use as video assist lenses: only a small portion of the light passes goes through the camera lens goes to the video chip. The lenses are not designed as zoom lenses because it would be impossible to get the same image quality and speed.

All academy optics are marked with an N in the serial number, e.g. N0040.

There is no difference between lenses for PAL and NTSC.

The CCD optic module, which is mounted on the ARRI- FLEX 535B’s viewfinder system, has to be equipped with a video lens. This module contains the CCD chip and all the necessary elements to center the video image on the TV-monitor screen and to adjust focus. It also houses a video pre-amplifier to increase the sensitivity of the IVS at low light conditions.

The CCD optic module is available in two versions for PAL or NTSC.

Note:

It is necessary to keep the combination of CCD

 

optic module and inserter/antiflicker module

 

together as delivered. Mixing the modules might

 

lead to reduced image quality.
