TCZRS series

8x bi-telecentric zoom lenses with motorized control

Catalog 2019

Available from March 2019

TCZR series is a leading edge optical solution for imaging and measurement applications requiring both the flexibility of zoom lenses and the accuracy of fixed optics.

An upgraded version of TCZR lenses, the newly designed TCZRS lenses feature an extremely precise positioning system with a bipolar stepper motor and an incremental magnetic encoder, delivering exceptional magnification repeatability. Moreover, focusing and image centering stability are guaranteed at every magnification position, thus avoiding recalibration at any given time.

Four different magnifications, featuring a total zoom range of 8x, can be selected through a dedicated remote control software.

Bi-telecentricity, high resolution and low distortion make these zoom lenses able to perform the same measurement tasks as classic telecentric lenses.

Notes

Working F/#: the real F/# of a lens when used as a macro. Lenses with smaller apertures (higher wF#) can be supplied on request.
Maximum slope of principal rays inside the lens: when converted to millirad, it gives the maximum measurement error for any millimiter of object displacement
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 3.45 μm.
Indicates the availability of an integrated camera phase adjustment feature.
