FOV = Field of view; HFOV = horizontal view; VFOV = vertical view; DFOV = Diagonal dimension of the total measuring field at the object level;
IFOV = Indicated field of view
Table with examples showing which measuring field sizes and pixel sizes are reached at which distance. Various lenses are available for optimal con-
figuration of the camera. Wide angle lenses have radial distortion due to the angle of their aperture. The TIMConnect software has an algorithm which
corrects this distortion.
* Please note: The measurement accuracy of the camera may lie outside of the specifications for distances below the defined minimum measurement
distance.
