This Standard specifies requirements for laser components used in the near-ultraviolet, visible and near-infrared spectral ranges, from 190 nm to 2100 nm and facilitates the supply of spare parts. It specifies preferred dimensions and tolerances for planer, plano-spherical and spherical substrates, lenses and optical components that are designed specifically as standardized optical components normally offered via catalogues from suppliers and intended for use with lasers.
