滤光镜 |
窄带滤光镜 |
窄带滤光镜设计用于在波长短于截止波长的一定波段内传输能量,
而在波长大于截止波长的情况下阻止能量传输.
阻止能量传输可以通过反射或吸收达到特定的衰减来实现.
窄带滤光镜的基本限制是有效传输区域的最大宽度接近截至波长的50%,
有效传输区域和衰减区域的复合宽度接近截止波长的90%. |

长带滤光镜 |
长带通滤光镜设计用于在阻挡波长小于截止波长的一切波长的光,
而传输大于截止波长的特定波段的光.
传输波段的长波长极限通常由系统探测器的波长极限决定.
长带通滤光镜通常用在光栅光谱仪里做级次分离,
带通滤光器中的短波截止器. |

激光线干涉滤光镜 |
激光线干涉滤光镜通过干涉效应来控制传输能量的光谱组成.
通常这些滤光镜由金属和介质的薄磨层组成,
形成窄光谱波段内的高透过率. |
