Ultra compact bi-telecentric lens for matrix detectors up to 2/3", magnification 0.044, C mount

Given the squared 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/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. 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 3.45 μm. Object side, calculated with the Rayleigh criterion with λ= 520 nm Indicates the availability of an integrated camera phase adjustment feature. Maximum dimension of the clamping flange.
