Supplementary information
The support mass defines the distance between the CCD chip and the support
surface of the lens. The support surface is the surface with which the lens lies on
the location thread of the (camera) housing. The lens has been calculated within
the framework of the CMount standard, so that the picture level lies exactly the
distance of the support mass behind the support surface and therefore exactly on
the CCD chip surface.
If required, the lens can be exchanged so that the photographing procedure can be
adapted to the specific task. The following specifications refer to the lens supplied.
The CHB−C−F is supplied from the factory with lens extension and preset lens:
