Notes

Working distance: distance between the front end of the mechanics and the object.
Working F/#: the real F/# of a lens in operating conditions.
Maximum angle between chief rays and optical axis on the object side.
Percent deviation of the real image compared to an ideal, undistorted image: typical (average production) values and maximum (guaranteed) values are listed.
At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 5.5 μm.
