USB650-VIS-NIR教學(xué)光譜儀

紅潮光譜儀是一個(gè)低費(fèi)用、小型化的實(shí)驗(yàn)室用光譜儀，是低預(yù)算的教學(xué)與研究實(shí)驗(yàn)室對(duì)于常規(guī)設(shè)備的理想選擇。USB650-VIS-NIR紅潮光譜儀的波長(zhǎng)范圍為350～1000nm，配有650有效像素的檢測(cè)器，可以在全光譜上顯示650個(gè)數(shù)據(jù)點(diǎn)，或者在每1nm上顯示一個(gè)數(shù)據(jù)點(diǎn)。由于配置了25 μm的入射光狹縫，紅潮光譜儀可以提供約2.0nm的光學(xué)分辨率（FWHM）。

產(chǎn)品特點(diǎn)

  • 集成度高，小巧，光譜范圍為350-1000nm， 2.0nm光譜分辨率(FWHM)
  • 吸光度測(cè)量靈敏度為0.1
  • 可直連海洋光學(xué)的氘燈和樣品池
  • USB 2.0接口

直連光源

USB650-VIS-NIR光譜儀可直連USB-ISS-VIS LED鹵燈光源和樣品池，光譜范圍為350-1000nm。該樣品池1cm見方，可用于吸光度測(cè)量。USB650-VIS-NIR可通過軟件來(lái)控制光強(qiáng)和開關(guān)。

模塊化設(shè)計(jì)

海洋光學(xué)提供完整的光纖及附件產(chǎn)品，可簡(jiǎn)單地通過SMA905接口和光譜儀連接，極大地增強(qiáng)了USB650-VIS-NIR光譜儀的應(yīng)用領(lǐng)域，其中CHEM4-VIS-FIBER光纖光譜儀可使用戶方便地連接各種附件，如反射探頭和透射探頭等。

即插即用

USB650-VIS-NIR通過USB2.0和電腦相連，可以非常迅速地傳輸數(shù)據(jù)。
