1) aperture diaphragm
孔径光阑
1.
Based on diffraction integral formula and selfreproducing principle,diffraction integral equation for transverse modes in a circular symmetric resonator with an aperture diaphragm was disintegrated to finitesum matrix equation,and field distributions of transverse modes in the resonator were calculated by solving matrix for eigenvalues and eigenvectors.
结果证明,孔径光阑的位置和尺寸直接影响激光输出模式和花样。
2) aperture
[英]['æpətʃə(r)] [美]['æpɚtʃɚ]
孔径光阑
1.
According to the basic relation E =φ/A, a direct optical method for aperture area measurement was provided, based on known constant irradiance over the aperture.
根据辐射照度与面积的基本关系,采用平行等间隔的相同激光束相互重叠,形成空间均匀的照度区域,且覆盖孔径光阑。
3) diaphragm aperture
光阑孔径
4) Stop,aperture.
孔径光阑，孔阑
5) aperture and stops

分子式：
CAS号：
性质：在摄谱仪的光学系统中限制光束立体角(截面积)成像的元件。如照明系统中的遮光板，它可防止光源电极头所发射出来的红热的白炽光进入狭缝。这种元件也包括狭缝，透镜的框边等部件。
