DIN EN ISO 11151-2:2015-12 EN ISO 11151-2:2015 (E) 3 IntroductionLasers are used in a wide variety of applications, including medicine, materials processing, informati
30、on 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 energy densities
31、to avoid laser-induced damage, thus their component specifications are more demanding than those used in low-power applications.DIN EN ISO 11151-2:2015-12 EN ISO 11151-2:2015 (E) 4 1 ScopeThis part of ISO 11151 specifies requirements for laser components used from near-infrared to mid-infrared, from
32、 wavelengths 2,1 m to 15,0 m, 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.This part of
33、 ISO 11151 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.This part of ISO 11151 includes component descrip
34、tions, 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, thi
35、s part of ISO 11151 does not include recommendations for the specification of coatings.NOTE The optical components used in the ultraviolet, visible, 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
36、 9211 (all parts).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

A wide range of materials may be used, such as zinc selenide, ZnSe,
43、potassium chloride, KCl, germanium, Ge, calcium fluoride, CaF2, silicon, Si, copper, Cu, 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 m
44、aterials used/required. The material specification shall be given as stated in ISO 10110-1:2006, 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.DIN EN ISO 11151-2:2015
45、12 EN ISO 11151-2:2015 (E) 6 5 Requirements for qualityPreferred specifications 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
46、that the material tolerances are inapplicable in the case of total reflector 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 o
47、f the incident radiation is scattered out of the beam by the imperfection. 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 no difference between a flat circular window, IWC, specification and an output coupler, IOC, specification in this waveband. It should be noted that the s
