The work of preparing International Standards is normally carried out through ISO technical committees. Each
19、 member body interested in a subject for which a technical committee has been established 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 Internationa

In particular the different approval criteria needed for the different t
21、ypes of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

28、. Most lasers contain optical windows and mirrors (intracavity) and most laser systems use a variety of windows, beamsplitters, deflectors, mirrors, and lenses. Those components used in high power laser applications have to withstand high peak power and/or energy densities to avoid laser-induced dam
29、age, thus their component specifications are more demanding than those used in low power applications.

30、ctral ranges1 ScopeThis part of ISO 11151 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 reducin
31、g 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 ISO 11151 covers planar, plano-spherical and spherical substrates, lenses, and optical components that are designed specifically as stand
32、ardized optical 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
33、most, but not all, of these components are 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 infrared spectra

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 indispensable for its application.

41、t of ISO 11151 is applicable to components employed in the ultraviolet, visible, and near infrared wavelength regions, 170 nm to 2 100 nm. A wide range of materials may be used, such as borosilicate crown glass, fused silica, UV-grade fused silica, and calcium fluoride.In view of the wide variety of
42、 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 10110-1:2006, 4.7. If birefringent materials are used/sp
43、ecified, the orientation of the optical axis relative to the geometric axes of the components shall be stated.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.
44、 The standard of quality for components 1) Currently under revision.2 ISO 2015 All rights reservedBS EN ISO 11151-1:2015ISO 11151-1:2015(E)to be used with lasers is in general higher than for general optics. There is also a quality requirement for optics to be used inside a laser cavity (intracavity
45、 use) distinctly different from that for optics used outside the laser cavity, due to the extremely high power and energy densities developed inside the laser cavity and the possibility of laser-induced damage.In consequence, this part of ISO 11151 promulgates two classes of quality. Class A optics
46、are designed for intra-cavity optics, output couplers, and for components used in areas of extremely high power (energy) density. Class A optics have significantly tighter form tolerance (3/.) and surface imperfection tolerance (5/.) figures than Class B optics. It should also be noted that the surf
47、ace dig and pit critical dimensions for laser-induced damage are /10 to 10, where is the wavelength of operation of the laser.NOTE The quoted grade values assume that most of the incident radiation is scattered out of the beam by the imperfection. This is the case where the radiometric obscuration e
48、quals 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 surface imperfections is described in ISO 14997 (see Bibliography).The differences between the material/fabrication tolerances for flat
49、 circular windows, WC, flat output couplers, OC, and flat mirrors, MF, and those for optical flats, OF, are due to the far higher fabrication tolerances for the latter and the fact that there is only one fabrication tolerance irrespective of the component diameter. The parallelism fabrication tolerances are (0 10) (angular seconds) for optical flats, while they are 1515+(angular minutes) for the other components. This is because optical flats are designed to generate con
