In a monochromator system there is normally also an exit slit, and only a narrow portion of the spectrum is projected on a one-element detector. In monochromators the entrance and exit slits are in a fixed position and can be changed in width. Rotating the grating scans the spectrum.Development of micro-electronics during the 90s in the field of multi-element optical detectors, such as Charged Coupled Devices (CCD) Arrays and Photo Diode (PD) Arrays。It enables fast scanning of the spectrum, without the need of a moving grating. 一般地，光谱仪由入射狭缝、准直镜、分光器（如光栅分光、棱镜分光）、凹面镜和检测器组成。在单色器分光系统中通常还有一个出射狭缝，狭缝仅通过很小光束，光束射到单通道检测器面。入射狭缝和出射狭缝虽位置固定于单色器台，但可以改变狭缝宽度，通过旋转光栅实现扫描光谱。90年代微电子的发展催生了检测波长范围更宽的检测器，例如电荷耦合器件CCD和二极管阵列检测器,扫描速度快，无需光栅动作。configure a spectrometer for your application根据应用目的而配置仪器In the modular design a number of choices have to be made on several optical components and options, depending on the application you want to use the spectrometer for. This section should give you some guidance on how to choose the right grating, slit, detector and other options. 根据光谱仪使用目的选择光学组件和配件，尽管器件已模块化。下面就如何选择正确的光栅、狭缝、检测器及其他给出建议如下：Wavelength Range波长范围In the determination for the optimal configuration of a spectrometer system the wavelength range is the first important parameter that defines the grating choice. 优配光谱仪的关键是分光（光栅），波长是第一个要考虑的因素。Optical Resolution 光学分辨率If you desire a high optical resolution we recommend to pick a grating that has 1200 or more lines/mm in combination with a narrow slit and a detector with 2048 pixels。如果希望分辨率高，可以选择1200线每毫米或更多，搭配使用小的狭缝和2048X1的检测器。Sensitivity灵敏度Talking about sensitivity, it is very important to distinguish between photomet
