Description
図4は非球面ミラー400の一例を示し、これは、反射性である第1の主面408を有し、また領域410に逆方向湾曲を有する。ミラー400のこのような湾曲は、図4の線5’‐5’に沿ったミラー400の断面図を示す図5において、より明瞭に確認できる。ミラー400は、第2の主面409の反対側の第1の主面408を有し、厚さtが第1の主面408と第2の主面409とを隔てている。領域410は、逆方向湾曲が存在する領域を強調している。逆方向カーブは、複合カーブの一種である。複合カーブは、交点において共通接線を有する2つ以上の弧からなる。逆方向カーブでは、2つの弧又はカーブが交点において1つの共通接線を共有し、従って湾曲の方向が、隣接するカーブの交点において変化する。逆方向カーブは、「S字型(s‐shaped)」カーブと呼ばれる場合もある。例えば図5では、第1のカーブは、湾曲の軸C1に関する第1の曲率半径R1によって画定され、第2のカーブは、湾曲の軸C2に関する第2の曲率半径R2によって画定される。上記第1及び第2のカーブは、変曲点412で交差し、この点においてこれらのカーブは出会い、ミラーの湾曲が方向を変化させる。なお、図5は正確な縮尺で描画されておらず、逆方向カーブの基本構造を例示するために使用される。本開示の1つ以上の実施形態では、ミラーは、図5に示されているように、接合して1つの逆方向カーブを形成する、2つの曲率半径を有する2つのカーブからなってよく、又は隣接するカーブによる1つ以上の逆方向カーブを含む、2つ以上の曲率半径の多数のカーブを備えてよい。 FIG. 4 shows an example of an aspheric mirror 400 that has a first major surface 408 that is reflective and has a reverse curvature in region 410 . Such curvature of mirror 400 can be seen more clearly in FIG. 5, which shows a cross-sectional view of mirror 400 along line 5′-5′ of FIG. The mirror 400 has a first major surface 408 opposite a second major surface 409 with a thickness t separating the first major surface 408 and the second major surface 409 . Region 410 highlights regions where reverse curvature exists. A reverse curve is a type of compound curve. A compound curve consists of two or more arcs that have common tangents at their intersections. In a reverse curve, two arcs or curves share a common tangent at the point of intersection, so the direction of curvature changes at the point of intersection of adjacent curves. Reverse curves are sometimes referred to as "s-shaped" curves. For example, in FIG. 5, the first curve is defined by a first radius of curvature R1 about axis of curvature C1 and the second curve is defined by a second radius of curvature R2 about axis of curvature C2. be. The first and second curves intersect at an inflection point 412, at which point they meet and the curvature of the mirror changes direction. Note that FIG. 5 is not drawn to scale and is used to illustrate the basic structure of the backward curve. In one or more embodiments of the present disclosure, the mirror may consist of two curves with two radii of curvature that join to form one opposite curve, as shown in FIG. Or it may have multiple curves of two or more radii of curvature, including one or more opposite curves with adjacent curves.
