With these wide l0 X comparators, it will not be necessary to guess over blemish sizes. Each unit can be adjusted to the eye of the user for maximum sharpness of image and minimum eyestrain. Simply focus the eyepiece on the reticle and hold the comparator in close proximity to the item being inspected. The depth of field of the achromatic eyepiece will bring the test item into focus without the need for actual physical contact with the work. The large reticles show Scratch increments of 10, 20, 40, 60 and 80, and Dig increments of 5, 10, 20, 40 and 50.

Scratch number indicates width of scratch in microns. Tolerances for scratch widths are:

#10 = 10 +/- 0.5u
#20 = 20 +/- 2.0u
#40 = 40 +/- 4.0u
#60 = 60 +/- 6.0u
#80 = 80 +/- 8.0u
