What is a spectrometer? A spectrometer is also called a spectrometer. A device for measuring the intensity of different wavelength positions of the spectral line with a photodetector such as a photomultiplier tube. Its structure consists of an entrance slit, a dispersion system, an imaging system and one or more exit slits. The dispersive element is used to separate the electromagnetic radiation of the radiation source into the required wavelength or wavelength region, and the intensity is measured at the selected wavelength (or scanning a certain band). A spectrometer is an instrument that detects and processes such changes by causing the electronic transition between the energy levels of atoms and molecules in the substance caused by the interaction between light and substance, causing the absorption, emission, and scattering of light by the substance to change in wavelength and intensity information. A spectrometer is a scientific instrument that decomposes light with a complex composition into spectral lines. It is composed of prisms or diffraction gratings. The spectrometer can measure the light reflected from the surface of an object. The seven-color light in sunlight is the part that can be divided by the naked eye (visible light), but if the sunlight is decomposed by a spectrometer and arranged according to wavelength, the visible light only occupies a small range in the spectrum, and the rest are spectrums that cannot be distinguished by the naked eye, such as infrared and microwave , Ultraviolet rays, X-rays, etc. Through the capture of optical information by spectrometer, development with photographic film, or computerized automatic display numerical instrument display and analysis, so as to determine what elements are contained in the article. As an important analysis method, the spectral analysis method is widely used in the detection of air pollution, water pollution, food hygiene, metal industry, etc., and plays a great role. Whether it is penetration absorption spectrum, fluorescence spectrum, Raman spectrum, how to obtain single wavelength radiation is an indispensable means. Because modern monochromators can have a wide spectral range (UV-IR), high spectral resolution (to 0.001nm) automatic wavelength scanning, complete computer control functions are easily integrated with other peripheral devices into high-performance automatic test systems, Using a computer to automatically scan a multi-grating monochromator has become the first choice for spectroscopic research. Spectroscope is a scientific instrument that decomposes light with complex composition into spectral lines. It is composed of prism or diffraction grating, etc. The spectrometer can measure the light reflected from the surface of the object. The seven-color light in sunlight is the part that can be divided by the naked eye (visible light), but if the sunlight is decomposed by a spectrometer and arranged according to wavelength, the visible light only occupies a small range in the spectrum, and the rest are spectrums that the human eye cannot distinguish, such as infrared and microwave , Ultraviolet rays, X-rays, etc. Through the capture of optical information by spectrometer, development with photographic film, or computerized automatic display numerical instrument display and analysis, so as to determine what elements are contained in the article. There are many types of spectrometers. In addition to the spectrometers used in the visible band, there are infrared spectrometers and ultraviolet spectrometers. According to different dispersive elements, it can be divided into prism spectrometer, grating spectrometer and interference spectrometer. According to the detection method, there are a spectroscope for direct observation with the eye, a spectrograph recorded with a photosensitive sheet, and a spectrophotometer with a photoelectric or thermoelectric element to detect the spectrum. A monochromator is a spectroscopic instrument that only outputs a single chromatographic line through a slit, and is often used in conjunction with other analytical instruments. This technology is widely used in the detection of air pollution, water pollution, food hygiene, metal industry, etc.
Goldstone is a man made gemstone that has been around since the European Rennaissance.
Early monks working at a glass factory near Venice, Italy were practicing alchemy when molten copper accidentally tipped into a molten glass container.
This crystallized into thousands of tiny crystals and formed a melt with golden light sparkles. This is how the first goldstone came about. Though it is not technically a gemstone, it is often referred to as one.
Goldstone is an energy stone.
