25、ieldun, na, Sun Nov 19 12:48:54 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through IS
26、O technical committees. Each 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 c
27、losely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulat
28、ed to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 11151 may be the subject of patent rights. ISO shall not be held re
29、sponsible for identifying any or all such patent rights. International Standard ISO 11151-1 was prepared by Technical Committee ISO/TC 172, Optics and optical instruments, Subcommittee SC 9, Electro-optical systems. ISO 11151 consists of the following parts, under the general title Lasers and laser-

31、Nov 19 12:48:54 GMT+00:00 2006, Uncontrolled Copy, (c) BSI v Introduction Lasers are used in a wide variety of applications, including medicine, materials processing, information technology and metrology. Most lasers contain optical windows and mirrors (intracavity) and most laser systems use a vari
32、ety of windows, beamsplitters, deflectors, mirrors and lenses. Those components used in high power laser applications must withstand high peak power and/or energy densities to avoid laser-induced damage, thus their component specifications are more demanding than those used in low power applications

34、d optical components Part 1: Components for the UV, visible and near-infrared spectral ranges 1 Scope This part of ISO 11151 specifies requirements for laser components used in the near ultra-violet, visible and near infrared spectral ranges, from wavelengths 190 nm to 2 100 nm, and facilitates the
35、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; ?by establishing an agreed designation for item orders. This part of ISO 11151 covers planar, plano-spherical and sphe
36、rical substrates, lenses and optical components that are designed specifically as standardized optical components normally offered via catalogue from suppliers and intended for use with lasers. Thispart ofISO 11151 includescomponent descriptions, materialsemployed, physicaldimensionsand manufacturin
37、g tolerances (including surface finish, figure and parallelism). Although 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 specific
38、ation of coatings. NOTE For optical components used in the infrared spectral range ( 2 100 nm), refer to ISO 11151-2. For the specification and testing of optical coatings, refer to the ISO 9211 series. 2 Normative references The following normative documents contain provisions which, through refere
39、nce in this text, constitute provisions of this part of ISO 11151. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 11151 are encouraged to investigate the possibility of applying the mos
40、t recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

43、 11151 is applicable.

A wide range of materials may be used, such as: ?borosilicate crown glass; ?fused silica;
45、?UV-grade fused silica; ?calcium fluoride. 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
46、as stated in subclause 4.7 of ISO 10110-1:1996. If birefringent materials are used/specified, the orientation of the optical axis relative to the geometric axes of the components shall be stated. 5 Requirements for quality Preferred specifications and classes for material and surface quality are set
47、 out in Tables 2 to 6, using terminology in accordance with parts 1 to 7 of ISO 10110. The standard of quality for components 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 use) distinc
48、tly 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.

49、controlled Copy, (c) BSI 3 In consequence this part of ISO 11151 promulgates two classes of quality1). Class A optics 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 do Class B optics. It should also be noted that the surface dig and pit critical dimensions for laser-induced damage are ?/10 to 10?, where ? is the
