22、ations in the form (shape) of an optical surface and provides a means of specifying tolerances for certain types of surface form deviation in terms of nanometres.As it is common practice to measure the surface form deviation interferometrically as the wavefront deformation caused by a single reflect
23、ion from the optical surface at normal (90 to surface) incidence, it is possible to describe a single definition of interferometric data reduction that can be used in both cases, i.e. in surface form deviation as well as wavefront deformation. As the analysis of most measurements is software based,
24、the deviations are expressed in nanometres. Interferometrical measurements, however, use the unit “fringe spacings”. One “fringe spacing” is equal to a surface form deviation that causes a deformation of the reflected wavefront of one wavelength. A value expressed in nanometres is an indication of t
25、he actual height deviation of the surface itself (and not that of the reflected wavefront).The surface under test, together with the test glass is, for example, such an interferometer. The surface form deviation is represented by the wavefront deformation which is the difference between the wavefron
26、t reflected by the actual surface and that reflected by the test glass surface.Due to the potential for confusion and misinterpretation, nanometres rather than fringe spacings are to be used. Where fringe spacings are used as units, the wavelength is also to be specified.In addition, tolerances for
27、slope deviations of surfaces can be given in units of mrad, rad, arcmin, or arcsec.DIN ISO 10110-5:2016-04 6 Optics and photonics Preparation of drawings for optical elements and systems Part 5: Surface form tolerances1 ScopeThis International Standard specifies the presentation of design and functi
28、onal requirements for optical elements and systems in technical drawings used for manufacturing and inspection.This part of ISO 10110 specifies rules for indicating the tolerance for surface form deviation.NOTE The terminology of interferometry employing the unit “fringe spacings” is widely used for
29、 the specification of tolerances. However, the usage of non-interferometric methods for testing of optical parts has recently become more important. Therefore, unlike in the earlier versions of this part of ISO 10110, nanometres shall now be the preferred and standard unit to express surface form de
30、viations. The usage of fringe spacings is still permitted given that the base wavelength is explicitly stated.This part of ISO 10110 applies to surfaces of plano, spherical, aspheric, circular and non-circular cylindric, and toric form as well as to surfaces of other non-spherical shape such as gene
31、rally described surfaces .Itdoes not apply to diffractive surfaces, Fresnel surfaces, and micro-optical surfaces.2 Normative referencesThe following referenced documents, in whole or in part, are indispensable for the application of this document.

38、tion are indicated by specifying the maximum permissible values of the power deviation, irregularity, rotationally and/or translationally invariant irregularity. In addition, tolerances for root-mean-square (rms) measures of surface form deviation (rms total, rms irregularity, and rms rotationally a
39、nd/or translationally varying wavefront irregularity) and tolerances for slope deviation (max and rms values) may be specified (see ISO 14999-4 for definitions). A surface form deviation based on a sagitta table can also be given in the z-direction and as irregularity as well as slope.Both the surfa
40、ce form tolerances and the tolerances of the slope deviations can vary in different sections and different orientations (x, y) or (, ). In this case, the sampling length and the spatial sampling interval can also deviate from each other.The surface form tolerance can also be defined as coefficients
41、of a Zernike polynomial.NOTE 1 ISO 10110-14 provides a means of specifying only one single tolerance for the wavefront deformation without any need to specify tolerances for individual surfaces.NOTE 2 Methods for determining the amount of power deviation, irregularity, rotationally and/or translatio
42、nally invariant irregularity, and slope deviation of a given surface are given in ISO 14999-4.Specifying a slope deviation tolerance or rms slope is recommended for non-spherical surfaces like aspheric, non-circular cylindric, or general surfaces. Depending on the application and complexity, the per
43、missible max slope deviation might also be indicated as an absolute quantity in direction (x, y) or (, ).It is not necessary that tolerances are specified for all types of surface form deviation.All deviations of the surface but one is defined perpendicular to the theoretical surface. The sagitta de
44、viation, Z, is defined along the z-axis.4.2 UnitsThe maximum permissible values for power deviation, irregularity, and rotationally and/or translationally invariant irregularity shall be specified in units of nanometres or, if preferred, micrometers or fringe spacings. If a specification is to be gi
45、ven for one or more rms deviation types, it shall be given in units of nanometres or, if preferred, micrometers or fringe spacings.To avoid confusion, the unit “wavelength of light” should never be used for surface form deviations.When a surface is tested interferometrically by reflection at normal
46、incidence, a surface form deviation of one-half the wavelength of light causes a wavefront deviation of one full wavelength. This results in an interference pattern in which the intensity varies from one bright fringe to the next or from one dark fringe to the next, i.e. one fringe spacing is visibl
47、e. For the purpose of this part of ISO 10110, the words “fringe spacings” do not refer to the transverse distance between fringes, but to the fact that the DIN ISO 10110-5:2016-04 8 number of fringe spacings visible in the interference pattern corresponds to the number of wavelengths of wavefront deviation.NOTE 1 One fringe spacing is 1 1/2 the wavelength (in nanometres) in which a surface form deviation is actually specified.NOTE 2 The specification of a tolerance for an rms deviation type requires that the
