Tiziani |\n\nISO 10110  \n1/25/2016  \nISO 10110‐1 General  \n• “Indications according to ISO 10110” appears on the drawing.  \n• The metric system for all linear dimensions is used, although the English system can be used as well, but needs to be indicated on the drawing. A comma is used instead of the decimal point.  \n• Standard language is English (UK) . Note: centring instead of centering, colour instead of color, metre instead of meter.  \n• Anything described as “normative” in standard means“mandatory”.  \n• Reference wavelength = 546.07 nm Mercury e line.  \n• Temperature = 22 ± 2° C  \n\n| ISO 10110‐1 Projection\u003Cbr>\u003Cbr>ISO 10110 Uses First Angle Projection.

Do not mix hatched and unhatched elements in same drawing. For multiple elements alternate orientation of hatching. |  |\n\n\n| ISO 10110‐1 Axes |  |\n| --- | --- |\n| | |\n| The center line is denoted by dash – dot line\u003Cbr>The optical axis (and light path through prism) is denoted by dash-dot-dot line. Often these are the same lines. |  |\n\n1/25/2016  \nISO 10110‐1 Leader Lines  \nLeader lines to an area are terminated with a dot. Leader lines to a surface are terminated with an arrow.  \nISO 10110‐1 Test Areas  \nTest regions or optically effective surfaces can be denoted on the part if the entire area does not need to meet some optical requirement. The diameter of circular test regions, the “effective diameter”, is indicated by“∅e”. It defines the region of the component surface which has optical significance.  \n1/25/2016  \nISO 10110‐1 Dimensioning  \nSpherical surfaces are defined by the radius of curvature with a dimensional tolerance . This tolerance indicates the range within which the actual surface is contained. The radius of curvature tolerance can also be defined by interferometry, but more on that later. For cylindrical surfaces, use Rcyl instead.  \nISO 10110‐1 Dimensioning  \nThe thickness is indicated as a nominal size with a (preferably symmetrical) tolerance. In the case of lens elements having concave surfaces, the overall thickness should be indicated within parenthesis in addition to the axial thickness.  \n1/25/2016  \nISO 10110‐1 Bevels & Chamfers  \nSharp Edge  \nBevel Chamfer  \nISO 10110‐1 Dimensioning  \nParts specified to have protective chamfers or small bevels are dimensioned without regard to the chamfers or bevels, i.e. the dimensions refer to the theoretical intersection of the surfaces (“sharp edge condition”) . Such dimensions shall be identified by appending “theor” to the indication.  \n1/25/2016  \nISO 10110‐1 Angles  \nUse capital Roman letters to indicate surfaces. The angles between surface E and the surfaces A, B, C and D are called “pyramidal angles”.  \nISO 10110‐1 Angles  \nFor prisms, the optical ray path and deflection angle may be shown. The deflection angle is the angle between the directions of the incident and emergent rays. Unless otherwise specified, the incident ray is perpendicular to the entrance surface. The deflection angle is given with a ± tolerance. An error in the ray deviation in the directions perpendicular to the plane of the drawing is known as “pyramidal deviation error”.  \n1/25/2016  \n\n| ISO 10110‐1 Materials Specs |\n| --- |\n| \u003Cbr>|\n\nISO 10110‐10 Properties  \n1/25/2016  \nDrawing Format  \nDrawing Example Singlet","cbCain9VVnEzq3Ea","https://ap.wps.com/l/cbCain9VVnEzq3Ea","pdf",395938,"English","# ISO 10110-1 General\n## Indications, language, and environmental settings\n## Projection and hatching\n## Axes and leader lines\n## Test areas and dimensioning\n## Bevels & chamfers and theoretical sharp edge condition\n## Angles and prism deflection conventions","[{\"question\":\"What does “normative” mean in ISO 10110-1 drawings?\",\"answer\":\"Anything described as “normative” in the standard means “mandatory”.\"},{\"question\":\"How should hatching be handled for optical elements?\",\"answer\":\"Elements can be unhatched or hatched; do not mix hatched and unhatched elements on the same drawing.
