Description
- Given the squared shape of the front window, the lens forms a rectangular image (Tech Info for related drawing).
- 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/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: maximum (guaranteed) values of the uncorrected image 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.
- Object side, calculated with the Rayleigh criterion with λ= 520 nm
- 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.
- 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.
