Each member body interested in a subject for which a technical committee has been established has the right to be repres

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are
11、drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 v

14、RNATIONAL STANDARD ISO 10937:2000(E)1 Optics and optical instruments Microscopes Diameter of interchangeable eyepieces 1 Scope This International Standard specifies the diameter of interchangeable eyepieces for microscopes. NOTE A specific combination of eyepiece, objective and tube lens is frequent
15、ly used to correct aberrations. Therefore the combination of an objective from one manufacturer and the tube lens or eyepiece from another manufacturer, although conforming to this International Standard, may cause errors in magnification and/or in optical performance. 2 Requirements The dimensions
16、of the eyepiece diameter shall comply with those given in Figure 1, however, the shape of the eyepiece does not necessarily have to correspond to the illustration. d = 23,2 mm h8; or d =3 0, 0mmh8 Figure 1 Diameter of the eyepieceBS ISO 7012-16:2001 ISO 10937:2000 BSI 389 Chiswick High Road London W
