根据现代光谱仪器的工作原理,光谱仪可以分为两大类:经典光谱仪和新型光谱仪.经典光谱仪器是建立在空间色散原理上的仪器;新型光谱仪器是建立在调制原理上的仪器.经典光谱仪器都是狭缝光谱仪器
According to the working principle of modern spectrometers, spectrometers can be divided into two categories: classical spectrometers and new spectrometers. Classical spectrometers are based on the principle of spatial dispersion; new spectrometers are based on the principle of modulation. Classical spectrometers are all slit spectrometers.
.调制光谱仪是非空间分光的,它采用圆孔进光根据色散组件的分光原理,光谱仪器可分为:棱镜光谱仪,衍射光栅光谱仪和干涉光谱仪.光学多道分析仪OMA (Optical Multi-channel Analyzer)是近十几年出现的采用光子探测器(CCD)和计算机控制的新型光谱分析仪器,
Modulation spectrometer is a non-spatial spectroscopic instrument. It uses circular aperture to enter light. According to the principle of dispersive components, spectrometers can be divided into prism spectrometer, diffraction grating spectrometer and interference spectrometer. Optical Multi-channel Analyser (OMA) is a photon detector (CCD) and computer-controlled optical multi-channel analyzer that has appeared in recent decades. New spectral analyzer,
它集信息采集,处理,存储诸功能于一体.由于OMA不再使用感光乳胶,避免和省去了暗室处理以及之后的一系列繁琐处理,测量工作,使传统的光谱技术发生了根本的改变,大大改善了工作条件,提高了工作效率;
Because OMA no longer uses photosensitive latex, avoiding and eliminating darkroom processing and a series of tedious subsequent processing, measurement work has fundamentally changed the traditional spectral technology, greatly improved the working conditions and improved the working efficiency.
