实验表明.镨钕玻璃在只改变单色光波长非空白调零(在721分光光度计上还可通过转动波长调节螺杆来实现)的条件下,529nm 处有一较尖锐的特征性吸收峰,同样可作为波长校正的依据。据此,建立了该波长校正法。1 方法1.1 用待校正的721分光光度计(下称光度计),蒸馏水调零,测试出镨钕玻璃529nm 吸收峰(下称镨峰)具
Experimental results show that praseodymium neodymium glass has a sharp characteristic absorption peak at 529 nm under the condition of only changing the monochromatic wavelength non-blank zero adjustment (which can also be realized by rotating the wavelength adjusting screw in the 721 spectrophotometer) Can be used as the basis for wavelength correction. Based on this, the wavelength correction method was established. 1 Method 1.1 To be corrected 721 spectrophotometer (hereinafter referred to as the photometer), zero water distilled to test the praseodymium neodymium glass 529nm absorption peak (hereinafter referred to as the peak of praseodymium) with
