WebScratch-dig specifications of 40-20 are widely considered standard quality for many optical applications. Precision laser applications typically require a scratch-dig of 20-10, whereas the most demanding laser applications, such as intra-cavity laser optics, usually require a scratch-dig of 10-5. WebThe standard only allows one dig of the stated maximum size per 20mm of lens diameter, and there are additional constraints, such as that if the dig number is 10 or less, every dig edge must be at least 1 millimeter away from the edge of its nearest neighbor. Bubbles are treated as digs. The scratch number is a less objective measurement.
