TC SERIES: BI-TELECENTRIC LENSES FOR MATRIX DETECTORS UP TO 2/3"

Bi-telecentric lenses are the key component of any accurate measurement system based on machine vision technologies.
Compatible with high resolution/small pixel detectors like 5Mpix 2/3" detectors, these lenses feature very low distortion while their real bi-telecentricity makes them purely telecentric.
It's easy to select the right lens for your application by means of its part number: for any given product P/N, i.e. TCxxyy, "xx" gives the camera sensor format size (13 = 1/3"; 12 = 1/2"; 23 = 2/3") while "yy" expresses the horizontal field of view (FOV) in millimeters.
For instance a TC 12 64 features a field of view of 64 (x 48) mm with a 1/2" camera sensor.

Notes
(1) Working Distance: distance between the front lens and the object. Set this distance within +/- 3% of the nominal value for maximum resolution and minimum distortion.
(2) Working F-number: the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request.
(3) Maximum slope of chief rays inside the lens: when converted to millirad, it gives the maximum measurement error for any millimeter of object displacement. Typical (average production) values and maximum (guaranteed) values are listed.
(4) Percent deviation of the real image compared to an ideal, undistorted image: typical (average production) values and maximum (guaranteed) values are listed.
(5) 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.
(6) Measured from the front end of the mechanics to the camera flange.
(7) With 1/1.8" (9 mm diagonal) detectors, the FOV of TC 12 XX lenses may show some vignetting at the image corners, as these lenses are optimized for 1/2" detectors (8 mm diagonal).
(8) For the fields with the indication "diam. =", the image of a circular object of such diameter is fully inscribed into the detector.
