| 1. | A very small lens aperture is employed to correct spherical aberration, but this severely limits the final resolution .
可以用一个非常小的透镜孔阑来校正球差，但这会严重地影响最终鉴别率。 |
| 2. | Set to the desired lens aperture
将镜头光圈调到您所希望的大小。 |
| 3. | The camera adjusts its focus , lens aperture , and shutter speed by itself
它会调焦、调光圈和光闸速度。 |
| 4. | Set to the desired lens aperture
设置所需的镜头光圈。 |
| 5. | Camera lens aperture
摄象机镜头孔阑 |
| 6. | Ratio of lens aperture
透镜孔径比 |
| 7. | Ccd iris , the function can automatically replace manual aperture lens aperture lens
Ccd iris ，该功能可以使手动光圈镜头替代自动光圈镜头。 |
| 8. | Ideally , a lens produces a circle of confusion that is simply a uniformly illuminated shape corresponding to that of the lens aperture
理想上，镜头产生形状和镜头光圈形状对应的均匀照亮的弥散圈。 |
| 9. | Another principle illustrated by figure 4 is that any object having edges that line up with the edges of the lens aperture will tend to be resolved to some degree
图四阐明的另一个原理是任何物体，只要它有边缘与镜头光圈边缘对齐，那么它的形状就能在一定程度上可以辨别。 |
