| XEL測(cè)試平臺(tái)光譜儀使用卓立漢光公司的Omni-λ3005,光譜波長(zhǎng)的校正采用傳統(tǒng)的汞燈譜線檢驗(yàn)技術(shù),所用LHM254汞燈光源屬于冷陰極低壓水銀放電燈,可提供253.65nm、312.57nm、313.15nm、313.18nm、365.02nm、404.66nm、435.84nm、546.07nm、576.96nm、579.07nm 等多條特征譜線。校正時(shí)先記錄所測(cè)汞燈譜線,檢驗(yàn)系統(tǒng)的分辨率與準(zhǔn)確度,然后通過(guò)軟件修正波長(zhǎng)誤差,最后多次重復(fù)測(cè)試,考察重復(fù)精度。校正結(jié)束時(shí)系統(tǒng)所測(cè)光譜的分辨率為0.1nm、波長(zhǎng)準(zhǔn)確度是0.2nm;重復(fù)精度達(dá)到0.1nm。 |

| The testing platform of XEL spectrometer using Zhuo Li Han Kuang 's Omni-λ 3005, the spectral wavelength correction using the traditional line inspection technology, the LHM254 mercury lamp light source of the cold cathode low-pressure mercury discharge lamp, can provide 253.65nm, 312.57nm, 313.15nm, 313.18nm, 365.02nm, 404.66nm, 435.84nm, 546.07nm, 576.96nm, 579.07nm and many of the characteristics of spectrum line. Correction to record the measured line, inspection system resolution and accuracy, and then through the software correction error of wavelength, and repeated testing, inspection precision. End correction system of the measured spectra resolution of 0.1nm, accuracy of wavelength was 0.2nm; repeat precision can reach 0.1nm. |
