Price based on 2 pages 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 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, govern- mental and non-governmental, in liaison with Iso, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISo Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 8037/1was prepared by Technical Committee ISO/TC 172, Optics and optical instruments. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latestedition,unlessotherwisestated.

This part of ISO 8037 contains requirements for dimensions, thickness and optical properties, whereas quality requirements and test methods related to the material will be dealt with in a future part of ISO 8037 Microscope slides form part of the illuminating system the task of which it is to illuminate the specimens, sometimes at very / large condenser apertures and often so as to form the additional S image of a diaphragm -- the so-called "field diaphragm" - in the specimen. When a specimen is being prepared, it is often completely left to the discretion of the user to decide which method of microscopy (bright field, dark field, phase contrast, interference contrast) will berequired for observation. Figure Microscope slides and condensers (parts of the illuminating optical system)should,therefore,besuitableforaspecimento be illuminated and observed whatever the method chosen. In 3.1.1 Length this context, it is important to keep to a certain refractive index and a certain thickness of the microscope slide, which together The length, I, for microscope slides shall be as given in the table. influence the quality of the image of the field diaphragm and the working distance between condenser and microscope slide 3.1.2 Width Scope and field of application The width, b, for microscope slides shall be as given in the table.
