ISO 11151-2:2015 specifies requirements for laser components used from near-infrared to mid-infrared, from wavelengths 2,1 µm to 15,0 µm, 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 11151-2:2015 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 11151-2:2015 includes component descriptions, materials employed, physical dimensions, and manufacturing tolerances (including surface finish, figure, and parallelism). Although most, but not all of these components will be coated (fully reflecting, partially reflecting, or anti-reflecting) before incorporation into the laser system, ISO 11151-2:2015 does not include recommendations for the specification of coatings.
