【摘要】：在光谱检测技术中所采用的光谱范围通常在紫外-可见光波段,同时要求该光源能够输出连续、稳定且光强较强的光,一般的单一光源很难满足这个要求.通常卤钨灯在可见光波段能很好的满足光谱检测分析,但在紫外波段无法满足要求.鉴于此,紫外LED灯可以弥补卤钨灯在紫外波段光强较弱的缺陷.为了实现紫外-可见光-近红外复合光源的设计,采用恒压输出驱动不同功率紫外LED灯,实现光谱光强的均匀性,最终设计成功一款小型紫外-可见光-近红外复合光源.
[Abstract]:The spectral range used in the spectral detection technology is usually in the ultraviolet-visible band. At the same time, it is required that the light source can output continuous, stable and intense light, so it is difficult to satisfy this requirement by a single light source. Usually the halogen tungsten lamp can satisfy the spectral analysis well in the visible band, but it can not meet the requirement in the ultraviolet band. In view of this, UV LED lamp can make up for the weak light intensity of halogen tungsten lamp in UV band. In order to realize the design of ultraviolet-visible-near infrared composite light source, constant voltage output was used to drive different power UV-LED lamp to achieve the uniformity of spectral intensity. Finally, a small UV-visible-near infrared composite light source was designed successfully.
