Imaging Field of View
When used for two-dimensional imaging applications, the I-PentaMAX camera closely
imitates a standard 35 mm camera. Since the CCD is not the same size as the film plane
of a 35 mm camera, the field of view at a given distance is somewhat different.

D = distance between the object and the CCD
B = 17.5 mm for C-mount; 46.5 mm for F-mount
F = focal length of lens
S = CCD horizontal or vertical dimension
O = horizontal or vertical field of view covered at a distance D
M = magnification
The field of view is:
This completes First Light. If the system functioned as described, you can be reasonably

certain situations, are discussed in the following chapters. See the appropriate
application software manual for information on using the software to control the system.
