Tamron LVZ3X3516N LWIR 3x Zoom Lens for VGA Detector

This new product has the lightest weight with a compact size that rivals any commercially available fixed focal telephoto lens. Designed in a compact chassis that provide versatility in installations, applications, and system integration. It covers most commonly used focal length range of 35-105mm, with a constant maximum aperture of F/1.6 throughout the entire range. Optical zoom is the best method for achieving the highest quality image magnification, but also convenient for setting up an ideal field of view for the area of interest. With these features, this product will allow the users to build a totally new surveillance system that is ideal for their application.
