ISO 11151-1:20 15规定了在紫外、可见光和近红外光谱范围（波长为170 nm至2 100 nm）中使用的激光组件的要求，并促进了备件的供应 通过指定优选的尺寸和公差，从而减少类型的多样性， 通过标准化规格和消除贸易壁垒，以及 通过为项目订单建立商定的名称。 ISO 11151-1:20 15涵盖平面、平球面和球形基板、透镜和光学元件，它们被专门设计为通常通过供应商目录提供的标准化光学元件，旨在与激光器一起使用。 ISO 11151-1:20 15包括部件描述、所用材料、物理尺寸和制造公差（包括表面光洁度、图形和平行度）。尽管这些部件中的大多数（但不是全部）在并入激光系统之前都经过涂层（全反射、部分反射或抗反射），但ISO 11151-1:20 15不包括涂层规范的建议。

ISO 11151-1:2015 specifies requirements for laser components used in the ultraviolet, visible, and near infrared spectral ranges, from wavelengths 170 nm to 2 100 nm, and facilitates the supply of spare parts

• by specifying preferred dimensions and tolerances, thereby reducing the variety of types,
• by standardizing the specifications and removing barriers to trade, and
• by establishing an agreed designation for item orders.

ISO 11151-1:2015 covers planar, plano-spherical and spherical substrates, lenses, and optical components that are designed specifically as standardized optical components normally offered through a catalogue from suppliers and intended for use with lasers. ISO 11151-1:2015 includes component descriptions, materials employed, physical dimensions, and manufacturing tolerances (including surface finish, figure, and parallelism). Although most, but not all, of these components are coated (fully reflecting, partially reflecting or anti-reflecting) before incorporation into the laser system, ISO 11151-1:2015 does not include recommendations for the specification of coatings.
