MZMT5x series motorized macro zoom lenses have been designed for inline applications where items of various sizes must be inspected with high resolution macro imaging. Unlike many zoom lenses, MZMT5x working f-number is constant when magnification is changed, thus ensuring high optical throughput even at high magnifications. MZMT5x models feature a total continuous magnification range of 5x and fit detectors up 4/3”, making them a very flexible solution to be used in many diverse applications. Opto Engineering motorization design integrates three bipolar stepper motors that respectively control zooming, focusing and iris with fine incremental movements and accurate repetitive positioning. MZMT5x moving parts are conveniently shielded and integrated within the lens barrel providing a zoom system that is both compact and robust. MZMT5x macro zoom lenses are complemented by dedicated stepper motor controller MTDV to be purchased separately. All of these features make these zoom lenses perfect for all those on-line applications requiring changes of format and high quality images.
