NIRQuest新型近紅外光譜儀
如果您希望使用近紅外光譜技術(shù)來做科研、過程控制和診 斷，NIRQuest近紅外光譜儀是一個(gè)，簡便的產(chǎn)品。 相比于海洋光學(xué)的舊的NIR光譜儀，NIRQuest使用了更的 光學(xué)平臺，具有更好的靈敏度和信噪比，同時(shí)也有更多的光柵供選擇。 NIRQuest具有多種版本可供選擇，包括 NIRQuest512(900－1700nm)，NIRQues256-2.1(900－2050nm)和 NIRQuest256-2.5(900-2500nm)。隨著新光柵的推出，將有更多的產(chǎn)品供您選擇。 |
使用NIRQuest和新光柵做激光分析
NIRQuest和新的光柵已經(jīng)可以滿足在近紅外范圍內(nèi)的激光分析使用了，的光學(xué)分辨率0.25nm(HWHM)。
