14H Optical Comparator

The Benchmark 14H is an Erect Image benchtop comparator. This new comparator has the same high quality features as the current product line, with an erect projection image and "ultra-precision" crossed roller bearing stage system, but in a smaller package. The measurement scales have zero backlash and are mounted in the center of the stage travel which provides maximum measurement accuracy. The optional extra long-life LED surface illumination is another Dorsey innovation.
