25、-04 6 Optics and photonics Preparation of drawings for optical elements and systems Part 12: Aspheric surfaces 1 Scope The ISO 10110 series specifies the presentation of design and functional requirements for optical elements in technical drawings used for manufacturing and inspection. This part of

26、ISO 10110 specifies rules for presentation, dimensioning and tolerancing of optically effective surfaces of aspheric form. This part of ISO 10110 does not apply to discontinuous surfaces such as Fresnel surfaces or gratings. This part of ISO 10110 does not specify the method by which compliance with

27、 the specifications is to be tested. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments

30、7: Surface imperfection tolerances ISO 10110-8, Optics and optical instruments Preparation of drawings for optical elements and systems Part 8: Surface texture 3 Mathematical description of aspheric surfaces 3.1 General 3.1.1 Coordinate system Aspheric surfaces are described in a right-handed, ortho

31、gonal coordinate system in which the Z axis is the optical axis. DIN ISO 10110-12:2016-04 7 Unless otherwise specified, the Z axis is in the plane of the drawing and runs from left to right; if only one cross-section is drawn, the Y axis is in the plane of the drawing and is oriented upwards. If two

32、 cross-sections are drawn, the XZ cross-section shall appear below the YZ cross-section (see Figure 5). For clarity the X- and Y-axes may be shown on the drawing. The origin of the coordinate system is at the vertex of the aspheric surface (see Figure 1). Figure 1 Coordinate system 3.1.2 Sign conven

33、tions NOTE !1“ As will be shown later in this part of ISO 10110, the various types of aspheric surface are given by mathematical equations. In drawings the chosen equation and the corresponding constants and coefficients are specified. To achieve unambiguous indications of the surfaces, sign convent

34、ions for the constants and coefficients need to be introduced. !NOTE 2 In this case, “left” and “right” presume z is increasing from left to right. When the Z-axis is reversed as a result of a reflection (a 180 rotation about the Y-axis), the sign convention for radius and sagitta is also reversed.

35、This is discussed further in 3.3.2.3.“ A radius of curvature (commonly given for the vertex) has a positive sign if the centre of curvature is to the right of the vertex and a negative sign if the centre of curvature is to the left of the vertex. The sagitta of a point of the aspheric surface is pos

36、itive if this point is to the right of the vertex (XY plane) and negative if it is to the left of the vertex (XY plane). DIN ISO 10110-12:2016-04 8 3.2 Classification of surface type Two types of surface are of particular importance because of their common application in applied optics: generalized

37、surfaces of second order; surfaces of higher order. Generalized surfaces of second order contain conical surfaces, centred quadrics and parabolic surfaces. Surfaces of higher order contain polynomials, toric surfaces and combinations of surface types, e.g. by adding polynomials to other surface type

38、s. 3.3 Special surface types 3.3.1 Surfaces of second order 3.3.1.1 Centred quadrics and parabolic surfaces In the coordinate system given in 3.1.1, the equation of the surfaces of second order which fall within the scope of this part of ISO 10110 are derived from the canonical forms nullnullnullnul

39、l+nullnullnullnull+nullnullnullnull=1 for centred quadrics (1)where a, b are real or imaginary constants; c is a real constant. nullnullnullnull+nullnullnullnull+2null=0 for parabolic surfaces (2)where a, b are real or imaginary constants, and can be written as null=null(null,null) =nullnullnullX+nu

40、llnullnullY1+null1(1+nullX)nullnullnullXnullnull (1+nullY)nullnullnullYnullnull(3)where RXis the radius of curvature in the XZ plane; RYis the radius of curvature in the YZ plane; X, Yare conic constants. DIN ISO 10110-12:2016-04 9 Using curvatures CX= 1/RXand CY= 1/RYinstead of radii yields null=nu

41、ll(null,null) =nullnullnullX+nullnullnullY1+null1(1+nullX)(nullnullX)null (1+nullY)(nullnullY)null(4)If the surface according to Equations (3) or (4) is intersected with the XZ plane (y = 0) or the YZ plane (x = 0), then, depending on the value of Y(or X), intersection lines of the following types a

42、re produced: 0 oblate ellipse; = 0 circle; 1 0 prolate ellipse; = 1 parabola; 1 hyperbola. The following special cases of Equations (3) and (4) should be mentioned: a) Rotationally symmetric surfaces: Using radii: Using curvatures:For R = RX= RY, = X= Yand h2= x2+ y2Equation (3) gives For C = CX= CY

44、or RY= Equation (3) gives For CX=0 or CY=0 Equation (4) gives null=null(null) =nullnullnullUnull1+null1(1+nullU)nullnullnullUnullnullnull(7)null=null(null) =nullnullnullU1+null1(1+nullU)nullnullnullUnull(8)Equations (7) and (8) describe a cylinder (due to Unot necessarily of circular cross-section),

45、 the axis of which for u = x is perpendicular to the XZ plane, and the axis of which for u = y is perpendicular to the YZ plane. DIN ISO 10110-12:2016-04 10 3.3.1.2 Conical surfaces The canonical form nullnullnullnull+nullnullnullnull+nullnullnullnull=0 (9)where a, b are imaginary constants; c is a

46、real constant. leads to Equation (10) null=null(null,null) =nullnullnullnullnullnull+nullnullnullnull(10)where a, b, c are real constants. This equation describes a cone with its tip at the origin, with elliptical cross-section (if a b) or with circular cross-section (if a = b). 3.3.2 Surfaces of hi

47、gher order 3.3.2.1 Polynomials The equation for polynomial surfaces is null=null(null,null) = nullnullnullnull+nullnullnullnull+ nullnullnullnull+nullnullnullnull+.+nullnull|null|null+.+nullnull|null|null+. (11)A special case of Equation (11) with h2= x2+ y2is null=null() = nullnullnull+ nullnullnul

48、l+ nullnullnull+. (12)!The first order and second order aspheric terms, A1h and A2h2, may be added to Equation (12).“ Equation (12) describes a rotational symmetric polynomial surface, known as Schmidt surface. 3.3.2.2 Toric surfaces A toric surface is generated by the rotation of a defining curve, contained in a plane, about an axis which lies in the same plane. The equation of a toric surface having its defining curve, z = g(x), in the XZ plane and its axis of rotation parallel to the X axis is null=null(null,null) =nullY nullnullnullYnull(null)nullnullnullnull(13
