* In this wide field-of-view lens the pixel size on the target increases towards the edges of the field of view due to spatial distortion, and thus the actual focal length depends on the spatial image size (detector size) used. Upon request, Middleton will provide the calibration file for the distortion in order to correct it in image processing.
