The Hastings Triplet Measuring Magnifier is a valuable tool whenever and wherever precision work is performed. The Hastings lens is adjustable for individual focus and provides a flat, distortion-free image. The transparent body allows illumination to fall on the magnified area. The protective case included keeps the magnifier safe and damage-free, even in harsh work environments. Available in either 7x or 10x magnification. A set of three different reticles are also available for this compact magnifier, which are interchangeable with the Bausch & Lomb ® Lenscope Lighted Magnifier.
