The work of preparing International Standards is
14、normally carried out through ISO 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
15、in the work. ISO collaborates closely 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 2. The main task of technical committees is to pre
16、pare International Standards. Draft International Standards adopted by the technical committees are circulated 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
17、some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10110-17 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 1, Fundamental standards. ISO 10110 consists
18、of the following parts, under the general title Optics and photonics Preparation of drawings for optical elements and systems: Part 1: General Part 2: Material imperfections Stress birefringence Part 3: Material imperfections Bubbles and inclusions Part 4: Material imperfections Inhomogeneity and st

For certain optical elements it may be necessary to specify the
31、state and plane of polarization as well as the angle of incidence. 5 Specifications 5.1 General Specifications of laser irradiation damage threshold apply to the finished surfaces, particularly surface treatments and coatings. BSISO1011017:2004 35.2 Damage threshold for pulsed laser irradiation The
32、specification of a laser irradiation damage threshold, H thor E th , for an optical surface shall include the laser wavelength, , and the effective pulse duration, eff . 5.3 Damage threshold for long pulse and continuous wave (cw) laser irradiation The specification of a laser irradiation damage thr
33、eshold, F th , for an optical surface shall include the laser wavelength, , and the effective pulse duration, eff . In case of cw-irradiation specify the irradiation time. NOTE In case of cw-lasers (i.e. irradiation time longer than 0,25 s according to ISO 11145) the effective pulse duration is not
34、defined and the term “irradiation time” is used. 6 Indication The laser irradiation damage threshold shall be indicated on the technical drawing by a code number and the parameters specified in Clause 5. Additional requirements shall be covered by notes. The code number for the laser radiation thres
35、hold is 6. The indication shall have the following form: a) for pulsed laser irradiation: 6/H th ; ; effor 6/E th ; ; effb) for long pulse and cw laser irradiation: 6/F th ; ; eff . The units of H th , E th , F th , and effshall be given in the indication. 7 Location The indication on the technical
36、drawing shall be shown in connection with a leader line to the surface to which it relates and will be associated with other surface codes (3/, 4/, 5/) as specified in ISO 10110-5, ISO 10110-6 and ISO 10110-7. An example of such an indication is shown in Figure A.1 of ISO 10110-1:1996. Alternatively
37、, the indication may be listed in a table according to Figure 3 of ISO 10110-10:2003. 8 Examples of indication EXAMPLE 1: 6/25 Jcm 2 ; 1 064 nm; 20 ns This means that the damage threshold is above an energy density of 25 Jcm 2 , for a laser wavelength of 1 064 nm (Nd:YAG) and an effective pulse dura
38、tion of 20 ns. EXAMPLE 2: 6/10 kWcm 1 ; 10,6 m; 1 s This means that the damage threshold is above a linear power density of 10 kWcm 1for a cw laser emitting at 10,6 m wavelength (CO 2 ) and an irradiation time of 1 s.
