This Ultra-Long Range Surveillance lens provides continuous motorized zoom for tracking objects at a distance from .7km to over 100km.  Ideal for weapons testing, shuttle tracking, and missile tracking, our Metric Zoom has the ability to image high speed events and conditions at locations that are far removed from the observer.  Accurately imaging a moving target under changing conditions requires either multiple imaging systems with fixed focal lengths or a zoom lens system that is capable of changing its magnification to accommodate the variation in object distance.  Our Metric zoom system offers significant advantages in that it eliminates the need for multiple imaging systems,  the costly task of changing fixed imaging systems during operations, and thereby reduces the costs and logistics of carrying multiple surveillance systems in inventory.
