TC12K series

Telecentric lenses for 12k and 16kpx line scan cameras

TC12K series telecentric lenses are designed to fit very large line detector cameras. An image circle diameter larger than 62 mm combined with the very high resolution featured by this lens family makes TC12K Series the solution of choice for 12 and 16k pixel cameras.

Flat panel display, solar cell and electronic board inspection are among the most common applications of these optics in the electronics industry; at the same time the optical specifications make them perfectly suitable for large mechanical parts accurate measurement.

In addition to the standard M72x0.75 mount, TC12K lenses can be easily equipped with any camera mount at no additional cost ensuring wide compatibility with most common linescan cameras.

Notes

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
Working F-number: the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request
Maximum slope of principal rays inside the lens: when converted to milliradians, it gives the maximum measurement error for any millimiter of object displacement
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 4.35 μm.
Measured from the front end of the mechanics to the camera flange.
FD stands for Flange Distance (in mm), defined as the distance from the mounting flange (the “metal ring” in rear part of the lens) to the camera detector plane.

Frequently asked questions

Wide image circle

TC12K is optimized to cover most of the line scan sensor sizes up to 62.4 mm.

Phase adjustment

Adjusting the phase of the camera mounted on TC12K telecentric lenses is easy: simply loosen the three set screws and rotate the camera mount until you achieve the desired angular alignment.
