The grating spectrograph is built in two designs . 光柵攝譜儀有兩種類型。
In the mass spectrograph the ions are focused onto a photographic plate . 在質(zhì)譜儀中,離子聚焦在感光板上。
A sample of each coating is exposed on an eastman 1b sensitometer and to a wedge spectrograph . 各涂層樣品用1B感光儀對著光楔攝譜儀曝光。
the spectrograph uses a concave diffraction grating that provides a wavelength dispersion of 4. 2a°/mm in the first order. 光譜儀用了一塊凹面衍射光柵,第一級光譜的色散度為42埃毫米。
The analysis of starlight with the spectrograph has provided information on the distances, temperatures, sizes, and notions of the stars . 用攝譜儀分析恒星的光譜,可提供恒星的距離、溫度、大小以及運動等方面的材料。
A spectrograph is an instrument that separates an incoming wave into a frequency spectrum. There are several kinds of machines referred to as spectrographs, depending on the precise nature of the waves.
