【摘要】：在光譜檢測技術(shù)中所采用的光譜范圍通常在紫外-可見光波段,同時(shí)要求該光源能夠輸出連續(xù)、穩(wěn)定且光強(qiáng)較強(qiáng)的光,一般的單一光源很難滿足這個(gè)要求.通常鹵鎢燈在可見光波段能很好的滿足光譜檢測分析,但在紫外波段無法滿足要求.鑒于此,紫外LED燈可以彌補(bǔ)鹵鎢燈在紫外波段光強(qiáng)較弱的缺陷.為了實(shí)現(xiàn)紫外-可見光-近紅外復(fù)合光源的設(shè)計(jì),采用恒壓輸出驅(qū)動不同功率紫外LED燈,實(shí)現(xiàn)光譜光強(qiáng)的均勻性,最終設(shè)計(jì)成功一款小型紫外-可見光-近紅外復(fù)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.
