Surface Quality Standards For Optical Filters

Surface quality specifications establish the acceptable flaws on coated or uncoated surfaces of optical components, influencing their performance. Various standards, such as military guidelines like MIL-PRF-13830B, define criteria like scratch-dig specifications (e.g., 60-40 indicating maximum scratch width). Proper specification of these standards is vital for balancing performance and cost; overly stringent standards or labor-intensive criteria can inflate expenses and affect yield.
