A spectrometer is a scientific instrument that decomposes light of complex composition into spectral lines, consisting of prisms or diffraction gratings, etc. Using a spectrometer, light reflected from the surface of an object can be measured. The seven colors of light in sunlight are the part that can be divided by the naked eye (visible light), but if the sunlight is broken down by a spectrometer and arranged by wavelength, visible light accounts for only a small range of the spectrum, and the rest are spectra that cannot be distinguished by the naked eye, such as infrared, microwave, ultraviolet, X-rays, etc.
Through the spectrometer to capture the light information, photographic negative development, or computerized automatic display value instrument display and analysis, so as to measure what elements contained in the goods. This technology is widely used in the detection of air pollution, water pollution, food hygiene, metal industry, etc. An optical instrument that separates complex light into a spectrum.
There are various types of spectrometers, including infrared and ultraviolet spectrometers, in addition to those used in the visible wavelength band. According to the different dispersive elements can be divided into prism spectrometer, grating spectrometer and interference spectrometer, etc. According to the detection method, there are spectroscopy with direct eye observation, spectrophotometer with photographic recording, and spectrophotometer with photoelectric or thermoelectric elements to detect the spectrum, etc.
A monochromator is a spectroscopic instrument that outputs only a single chromatographic line through a slit, and is often used in conjunction with other analytical instruments. The parameters that characterize the basic characteristics of a spectrometer are spectral range, dispersion, bandwidth and resolution capability. Spectrometers designed based on the interference principle have high dispersion and resolving power, and are often used for the analysis of fine structures in spectra.
The spectral analyzer is the basic structure of a trigonal prism regulator. The slit S is perpendicular to the main cross-section of the prism and is placed in the object-side focal plane of the lens L. The photoreceptor is placed in the image-side focal plane of the lens L. The light source is used to illuminate the slit S, and the image of S becomes a spectral line on the photoreceptor, and due to the dispersion effect of the prism, the spectral lines of different wavelengths are separated from each other, and the spectrum of the incident light is obtained. Prism spectrometer can observe the spectral range is determined by the absorption of optical components such as prisms on the spectrum.
Ordinary optical glass is only suitable for the visible band, with quartz can be extended to the ultraviolet region, in the infrared region generally use sodium chloride, potassium bromide and calcium fluoride and other crystals. The spectral range of reflectance grating spectrometers in common use today depends on the design of the grating stripe and can have a wide spectral range.
