18、ization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establish
19、ed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

27、ssing, information technology, and metrology. Most lasers contain optical windows and mirrors (intracavity) and most laser systems use a variety of windows, beam splitters, deflectors, mirrors, and lenses. Those components used in high-power laser applications must withstand high-peak power and/or e
28、nergy densities to avoid laser-induced damage, thus their component specifications are more demanding than those used in low-power applications.

29、 for the infrared spectral range1 ScopeThis part of ISO 11151 specifies requirements for laser components used from near-infrared to mid-infrared, from wavelengths 2,1 m to 15,0 m, and facilitates the supply of spare parts by specifying preferred dimensions and tolerances, thereby reducing the varie
30、ty of types, by standardizing the specifications and removing barriers to trade, and by establishing an agreed designation for item orders.This part of ISO 11151 covers planar, plano-spherical, and spherical substrates, lenses, and optical components that are designed specifically as standardized op
31、tical components normally offered through a catalogue from suppliers and intended for use with lasers.This part of ISO 11151 includes component descriptions, materials employed, physical dimensions, and manufacturing tolerances (including surface finish, figure, and parallelism). Although most, but
32、not all of these components will be coated (fully reflecting, partially reflecting, or anti-reflecting) before incorporation into the laser system, this part of ISO 11151 does not include recommendations for the specification of coatings.NOTE The optical components used in the ultraviolet, visible,
33、and near infrared spectral ranges (170 nm to 2 100 nm) is referred to ISO 11151-1. The specification and testing of optical coatings is referred to ISO 9211 (all parts).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensab

A wide range of materials may be used, such as zinc selenide, ZnSe, potassium chloride, KCl, germanium, Ge, calcium fluoride, CaF2, silicon, Si, copper, Cu,
41、 and Sapphire, Al2O3.In view of the wide variety of materials available, the use of specific code numbers for each material has not been formalized. Manufacturers and designers shall therefore specify the exact materials used/required. The material specification shall be given as stated in ISO 10110
42、-1:2006, 4.7. If birefringent materials are used/specified, the orientation of the optical axis relative to the geometric axes of the components shall be stated.1) Currently under revision.2 ISO 2015 All rights reservedBS EN ISO 11151-2:2015ISO 11151-2:2015(E)5 Requirements for qualityPreferred spec
43、ifications and classes for material and surface quality are set out in Tables 2 to 6, using terminology in accordance with ISO 10110-1 to ISO 10110-7. The same quality standards apply to all components of a given diameter, except that the material tolerances are inapplicable in the case of total ref
44、lector substrates.The requirement of quality for components to be used with infrared lasers is in general high; therefore this part of ISO 11151 only promulgates one class of quality.NOTE The quoted grade values assume that most of the incident radiation is scattered out of the beam by the imperfect
45、ion. This is the case where the radiometric obscuration equals the area obscuration. If the imperfection is partially transmitting, its actual area could be larger than is suggested by these values. A method for measuring the surface imperfections is described in ISO 14997.For this reason, there is
46、no difference between a flat circular window, IWC, specification and an output coupler, IOC, specification in this waveband. It should be noted that the surface dig and pit critical dimensions for laser-induced damage are /10 to 10, where is the wavelength of operation of the laser.Table 2 Material
