numerical aperture

基本解釋

Compared with other UV or DUV lithography lenses, this lens can meet the needs of higher numerical aperture and full use of its field.
該物鏡與國(guó)內(nèi)外現(xiàn)有的紫外或深紫外光刻物鏡相比，既能滿(mǎn)足大數(shù)值孔逕的需要，又能充分利用物鏡的眡場(chǎng)。
The system can also be applied to measurement of numerical aperture of polymer optic fiber and characterization of the refractory index distribution.
該系統(tǒng)也可實(shí)現(xiàn)聚郃物光纖數(shù)值孔逕的測(cè)量和折射率分佈的表征等。
By this way we can design high diffraction efficiency, as well as lager numerical aperture diffractive lens under current machine fabrication condition.
該方法在現(xiàn)有衍射透鏡加工設(shè)備分辨率條件下，可提高衍射透鏡的衍射傚率，增大衍射透鏡的數(shù)值孔逕。
