10-5 Scratch / Dig
|
|
A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width.
A scratch is a defect on a polished optical surface whose length is many times its width. 10 / 5 indicates the average diameter of the digs to be .05 mm and the average length of a scratch is .10 mm.

20-10 Scratch / Dig
|
|
A dig is a defect on a polished optical surface that is nearly equal in terms of its length and width.
A scratch is a defect on a polished optical surface whose length is many times its width. 20 / 10 indicates the average diameter of the digs to be .10 mm and the average length of a scratch is .20 mm.
