High resolution telecentric lens for 4/3″ sensors, magnification 0.122x, C mount

With IMX387 (21.7 mm diagonal) sensors, the FOV may show some vignetting at the image corners. 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 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. Measured from the front end of the mechanics to the camera flange.
