PDF file2. ISO 10110 and its implementation The ISO 10110 standard is the normative standard for NIF optics drawings. The ISO 10110 standard covers nearly all of the traditional optical element and system specifications in optics drawings. Table 1 shows the structure of the ISO 10110-1 standard.

The rating is formatted as two numbers separated by a hyphen, or sometimes a slash, for example 80-50. The first is the scratch number and the second the dig number.¹The dig number is the diameter, measured in hundredths of a millimeter,of a circle which would enclose the biggest dig in the surface numbers are the actual diameters of defects..See more on sizes

PDF fileStandard ISO 10110-7 Features ISO 10110-7 lists a number of standard features to be included in a Scale Comparison Plate. These features are listed in Annex E of the standard, and are reprinted in this guide in Table 4.2. The ISO 14997 Scratch Dig Standards include all of the features described by the standard. These features are explained below:

Understanding Surface Quality Specifications | Edmund Optics
ISO 10110-7 makes no distinction between scratches and digs and instead treats both simply as surface imperfections. 2 Rather than scratch-dig numbers, the 10110-7 indicates the number of allowed imperfections (N g) and a grade number (A g) which is equal to the square root of the area of the maximum allowed imperfection (Figure 4).

Another issue with ISO 10110 is that its surface inspection, much like the dimensioned Scratch/Dig standards, requires the use of a microscope to do it properly. Dedicated software that can quickly calculate the size and dimensions of surface defects then becomes necessary; a fully integrated and dedicated system can be an outstanding tool, but such systems can also be very expensive.
ISO - ISO 10110-7:2008 - Optics and photonics
ISO 10110-7:2008 applies to transmitting and reflecting surfaces of finished optical elements, whether or not they are coated, and to optical assemblies. It recognizes that permissible imperfections may be specified according to the area affected by imperfections on components or in optical assemblies.Category: w

Lots of people have tried to extend the usefulness of the scratch-dig standard by adding higher brightness light sources and magnification, which has caused more confusion. In 1996, with the publication of ISO 10110, there was an alternative.Cited by: 14Publish Year: 2010Author: David M. Aikens
