Opto Engineering TCZRS

Bi-telecentric zoom lenses with motorized control



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 centring 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.
