1 适用范围本标准适用于作标准角度规用的多面镜(以下称多面镜)。2 术语及定义本标准所使用的主要术语的含义如下:1)多面镜把正直棱柱的所有侧面作为反射面的反射镜的总称。正N直棱柱的场合,称为N面镜。2)底面垂直于反射面、把多面镜设置在旋转台上时所使用的平面。3)初始反射面在表示各反射面的公称角度时作为初始值的反射面。4)有效反射面反射面实际使用的范围。不加护罩时为整个反射面;带护罩时为罩的开口部分。
1 Scope This standard applies to the standard angle of the polygon mirror (hereinafter referred to as polygon mirror). 2 Terms and Definitions The main terms used in this standard mean the following: 1) polygon mirror All the sides of the prism as a reflection of the general reflector. N positive prism is the occasion, known as N-mirror. 2) Plane with the bottom surface perpendicular to the reflecting surface and the polygon mirror set on the turntable. 3) The initial reflection surface is the initial reflection surface when the nominal angle of each reflection surface is represented. 4) Effective reflection surface The actual range of reflection surface. The entire reflective surface without the hood; with the hood for the opening part of the hood.
