一、线光谱特性目前广泛采用的是具有原子发光线光谱的气体放电光源。既有单一元素发光的水银灯、钠灯,也有多种元素的金属卤化物灯。所谓线光谱,就是指辐射功率集中于非常狭窄波长范围内的光谱。一般来说,低气压放电,其发 First, the line spectral characteristics Currently widely used is the atomic emission line gas discharge light source. Both single-element light-emitting mercury lamps, sodium lamps, there are many elements of the metal halide lamp. The so-called line spectrum, refers to the radiation power concentrated in a very narrow wavelength range of the spectrum. In general, low pressure discharge, its hair
