Motorized bi-telecentric zoom lens
0.125 to 1x magnification
Repeatable positioning

The Opto-Engineering TCZR072S bi-telecentric lens with motorized zoom delivers both flexibility and precision. The internal stepper motor adjusts between four pre-set magnifications: 0.125, 0.250, 0.500, and 1.000. This lens is designed for cameras with up to a 2/3 format sensor.


This motorized zoom lens enables the magnification to be set by software. Thus, your system can measure or locate large features, and then zoom in to image fine object detail. It requires no more than two seconds to switch from any of the four available magnifications.


The precise positioning system eliminates any need to re-calibrate or refocus after changing magnification. This lens is bi-telecentric, meaning it is telecentric in both object space and image space. The bipolar stepper motor with incremental magnetic encoder delivers exceptional repeatability.

Motor controller, power supply and cable are sold separately. Please see Accessories below.
