应用在大能量多元件红外系统的光学元件的公差比那些通常使用在可见光谱区的高质量光学系统的光学元件的公差要求更为严格。此外,要求仪器商在此种情况下抛光非普通材料以获得最小的表面吸收和高的激光损伤抗力以及好的光学图形。红外激光系统用的元件和一些主要考虑散射光的较普遍应用的元件常常也要求极小的微粗糙度和刮痕密度。因此,正在发展高度满足这些经常矛盾的要求的技术。
Tolerances of optical components used in high-energy multi-component infrared systems are more stringent than those of optical components of high-quality optical systems that are commonly used in the visible region. In addition, instrumentation vendors are required to polish non-ordinary materials in such situations for minimal surface absorption and high laser damage resistance as well as good optical patterns. Components for infrared laser systems and some of the more commonly used components that primarily consider scattered light often also require minimal micro-roughness and scratch density. Therefore, technologies are highly developed to meet these often contradictory requirements.
