Working distance: distance between the front end of the mechanics and the object. Set this distance within ±3% of the nominal value for maximum resolution and minimum distortion. | Working f-number (wf/N): the real f-number of a lens in operating conditions. | Maximum angle between chief rays and optical axis on the object side. Typical (average production) values and maximum (guaranteed) values are listed. | Percent deviation of the real image compared to an ideal, undistorted image. Typical (average production) values and maximum (guaranteed) values are listed. | At the limits of the depth of field, the image can still be used for measurements. For a very sharp image, however, only half of the depth of field should be considered. Pixel size used for calculation is 3.45 μm. | Object side, calculated with the Rayleigh criterion with λ= 520 nm | Indicates the availability of an integrated camera phase adjustment feature. | Measured from the front end of the mechanics to the camera flange.
