holographic concave grating

基本解釋

Design of a dispersing system based on a multi channel detector and a flat field holographic concave grating.
采用平場(chǎng)凹面全息光柵和多通道檢測(cè)器設(shè)計(jì)了一個(gè)小型的色散系統(tǒng)。
A method which is based on Rowland mount and use ZEMAX software to design flat field holographic concave grating is given in this article.
介紹一種從羅蘭圓結(jié)構(gòu)出發(fā)，利用ZEMAX光學(xué)軟件設(shè)計(jì)平場(chǎng)全息凹面光柵的方法。
Comparing this spectrograph to the one with a holographic concave grating on spherical surface, the former has a higher resolution than the latter has when the widths of the incident slits are same.
與采用相同口徑、相同相對(duì)孔徑的全息凹球面光柵構(gòu)成的平場(chǎng)光譜儀比較，在入射狹縫寬度相同的情況下，該光柵所構(gòu)成的平場(chǎng)光譜儀的分辨率得到明顯提高。
