The work of preparing International Standards is
10、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 nongovernmental, in liaison with ISO, also take part i
11、n the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular
12、the different approval criteria needed for the different types 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 doc
13、ument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.o

16、 second edition cancels and replaces the first edition (ISO 109361:2000), which has been technically revised. The main changes compared to the previous edition are as follows: the normative references and the title have been updated; note from environmental conditions (4.3) has been removed; safety
17、requirements (4.4) have been updated; the requirement depths of field and total visual magnification (see Table 1) have been clarified.A list of all parts in the ISO 10936 series can be found on the ISO website.iv ISO 2017 All rights reservedBS ISO 109361:2017Optics and photonics Operation microscop
