Telecentric zoom lens for 2/3″ sensors with integrated liquid lens, manification range from 0.18x to 0.55x

Working distance: distance between the front end of the mechanics and the object, reported at nominal range of the liquid lenses; maximum excursion may be larger. 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. Percent deviation of the real image compared to an ideal, undistorted image. 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. Object side, calculated with the Rayleigh criterion with λ= 520 nm Typical at 30°C, 0 to ±250 mA step. Indicates the availability of an integrated camera phase adjustment feature. Measured from the front end of the mechanics to the camera flange.
