Telecentric lens for 2/3″ sensors with integrated liquid lens, mag. 0.243x
Optical Imaging Technologies for Machine Vision
Opto Engineering : TCEL23036
Description
Field of views are calculated at 0 dpt power of the liquid lens. Working distance (nominal): distance between the front end of the mechanics and the object at 0 pdt power of the liquid lens. Minimum and maximum working distance are reported at nominal range of the liquid lens; 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, evaluated at 0 dpt power of the liquid lens. Typical (average production) values and maximum (guaranteed) values are listed. Maximum values calculated in the range -2 to +3 dpt of the liquid lens. Percent deviation of the real image compared to an ideal, undistorted image, , evaluated at 0 dpt power of the liquid lens. 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 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.
