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

Opto Engineering Matrix Detector 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 5.5Mpix 2/3" detectors, these lenses feature extremely 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 part number, 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 an ½ inch camera sensor.

Notes
(1) Working Distance: distance bewteen 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) 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
(4) Maximum slope of principal rays inside the lens: when converted to millirad, it gives the maximum measurement error for any millimiter of object displacement
(5) Measured from the front end of the mechanics to the camera flange
(6) For the fields with the indication "diam. =" the image of a circular object is inscribed inside the short side of the detector
(7) The 1/1.8" (9 mm diagonal) FOV for TC 12 XX lenses can show some vignetting at the image corners, as the lens is optimized for 1/2" detector (8 mm diagonal)
