Non programming qn - How to obtain camera field of view ?

edit

I read up this equation on wikipedia https://en.wikipedia.org/wiki/Angle_o... i.e. a camera's angle of view can be found from the following equation

angle of view = 2 arctan ( d / 2f )

where f = focal length and d = size of film or sensor.

I am now trying to find the field of view of this camera https://www.ptgrey.com/flea2-14-mp-co.... The size of the sensor / film is not given but what are given are the pixel size and the resolution. Would the film size simply be the pixel size * the resolution ? This is an image taken by that camera btw.
