The Marco lensometer lens holder is the arm that swivels into place to hold the lens or frame stable while taking a reading. The circular piece on the end that swivels is referred to as a gimbal.
A non-scratch gimbal on the end of a spring loaded arm serves to hold the lens against the lens stop, which is also made of a non-scratch material. Both the gimbal and the lens stop should be kept free of dirt and dust as an additional precaution when working with plastic lenses.
