The theoretic value of the focal length calculation serves to find the best suitable optics. Typical increments of focal lengths for C-mount lenses are e.g. (1.8, 2.8, 4, 6,) 8, 12, 16, 25, 35, 50 and 75 mm.

The focal length f´ virtually serves to calculate the required lens and is thus the most important specification to characterise an (entocentric) normal lens.

A standard 1/4" format imager has an active area of 3.6mm x 2.7mm with diagonal size of 4.5mm.  This is one of the most popular formats for consumer, security and automotive cameras. To cover the entire imager active area the lens image circle must be greater than the imager diagonal.  Download application note on imager circle vs. active area.
