Parts are available in frequency ranges of 0.25 to 5 cy/mm, 2.5 to 50 cy/mm, and 25 to 500 cy/mm.
Lines and spaces for which the equivalent cycles per mm increases as the function of linear position; with each bar and space progressively smaller size, by Linear change of the c/mm value. Ideally suited for sensing & scanning equipment.
