MX Cameras Lens Specifications
The following sections provide technical specifications for the
different types of lenses available for Vicon MX cameras. For details
of specific lenses, contact Vicon Motion Systems or your nearest agent
or distributor.
MX cameras are fitted with lenses suitable for the type of application
you specified that the system is intended to be used for. If you wish
to change the supplied lens, you must consider various factors,
including the Field of View (FOV), the aperture, and any lens filter
fitted. A significant factor in the field of view is the image circle that
the camera lens casts onto the sensor size of the new lens. For
optimum performance, the image circle projected should be larger
than the sensor area used by the camera. For details on these factors
influencing the choice of camera lens, see Chapter 3 MX Cameras.
Table D-6 lists the image circle diameter produced by the C-mount
lens formats (1", 2/3", and 1/2") and the 35 mm SLR format lens
appropriate for use with Vicon cameras.
Table D-7 lists the necessary image circle diameter for each
MX camera at maximum resolution.
