Vicon MX Hardware System Reference D-7

By comparing the image circle details in these two tables, you can use

the information in the following sections to select a lens capable of

producing the image circle diameter required for the specified type of

MX camera.

For example, you can see from the tables above that no C-mount lens

format projects an image circle large enough to fully use the sensor

in an MX40+, MX40, MX13+, or MX13 camera. A 1" C-mount sensor

format is appropriate for an MX20+ camera, and 2/3" and 1" C-mount

sensor formats are appropriate for an MX3+ or MX3 camera.

For the larger format MX40+, MX40, MX13+, or MX13 cameras, SLR

format lenses are more suitable than C-mount lenses. SLR lenses are

designed for use with 35 mm film, or equivalent digital sensors. This

format projects a larger image circle than C-mount lenses. As you can

see from the tables above, lenses designed for these formats project

an image circle large enough for the MX40+, MX40, MX13+, and

MX13 cameras.

In some applications, a large field of view may be the overriding

requirement. In such cases, it may be appropriate to use a wide angle

C-mount lens on a larger format MX40+, MX40, MX13+, or MX13

camera. However, be aware that such lenses project an image circle

too small for the sensor. Therefore, you must determine whether the

benefits of the wide angle lens outweigh the inability to use the full

sensor area.
