Notes

Since the square shape of the front window the lens forms a rectangular image
Working distance: distance between the front end of the mechanics and the object. Set this distance within +/- 5% of the nominal value for maximum resolution and minimum distortion.
Working F-number (wF/#): the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request. Typical (average production) values and maximum (guaranteed) values are listed .
Maximum slope of chief rays inside the lens: when converted to millirad, it gives the maximum measurement error for any millimeter of object displacement. Maximum (guaranteed) values are listed.
Percent deviation of the real image compared to an ideal, undistorted image. Maximum (guaranteed) values are listed.
Residual distortion after calibration with TCLIB Suite software library, using a PTCP calibrations pattern and a fully GenICam® compliant camera. For setup information see related table.
At the borders of the field depth the image can be still used for measurement but, to get a perfectly sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.45 μm.
Indicates the availability of an integrated camera phase adjustment feature.
Maximum dimension of the clamping flange.
Measured from the front end of the mechanics to the camera flange.

Notice:
Due to its original design mainly conceived to reduce the length and weight of a telecentric lens, typically CORE PLUS optics show a thermal drift which is higher than in traditional telecentric optics, especially when the entire FOV is used for measurement. When used for measurement applications, thus, CORE PLUS optics might need to be thermally calibrated depending on the required precision and accuracy.
