ENMT series are high resolution fixed focal length lenses with automated adjustment of focus and aperture. These motorized lenses guarantee precise and repeatable adjustment of both the aperture and focus to realize fully automated systems. This feature is ideal for installations where remote operation is necessary (e.g. in clean rooms where an operator cannot manually adjust the optical parameters), besides those requiring possibility to change format, lighting conditions, working distance or even inspection task. Additionally, different machines can be set with the exact same aperture/focus setting by automatically loading a pre-set configuration. Thanks to ENMT precise motorized design, the user can fully exploit the high resolution of ENMT fixed focal length optics. In fact, when compared to coarse manual operation, motorized adjustment allows for very fine and repeatable tuning of both the image focus and F-number setting. Opto Engineering® motorization design integrates two bipolar stepper motors that respectively control focusing and aperture with fine incremental movements and accurate repeatable positioning. ENMT moving parts are conveniently shielded and integrated within a compact and robust enclosure. Focus and aperture can be adjusted by means of dedicated MTDV controller (available separately) specifically designed to drive up to four bi-polar stepper motors via Ethernet (TCP/IP). ENMT series integrate high resolution optics featuring minimum distortion and 11 mm image circle for 5 Megapixel detectors up to 2/3”.
