Almost all the spectrometers employed in industry are used for this purpose . 几乎所有工业部门的光谱仪器均用于这一目的。
Grating spectrometers, used over the ranges from soft x-rays to the far infrared, have enjoyed continued interest . 使用范围从软x射线到远红外线的光栅光谱仪继续受到注意。
the spectrograph uses a concave diffraction grating that provides a wavelength dispersion of 4. 2a°/mm in the first order. 光谱仪用了一块凹面衍射光栅,第一级光谱的色散度为42埃毫米。
