The RamanProbe IITM 
RamanProbe II是用于基于原始拉曼探頭的光學元件進行浸沒分析的通用光纖探頭。 8“長的主體和可拆卸的套筒使探頭可以直接浸入解決方案中進行的原位分析。可以選擇焦距以優化黑暗或混濁溶液的測量。 標準浸入式套管由不銹鋼制成，帶有藍寶石窗。 總體而言，探頭的直徑為5/8“，足夠小，可以放置在典型的實驗室規模的容器內?？梢钥焖僖瞥淄?，以便常規測量瓶子中的純固體或樣品。 下載（需要Adobe®Acrobat Reader）： 技術說明＃13：拉曼光纖采樣探頭的背景濾波 拉曼探針II規格表 特點和規格 Sampling Head | Stainless-steel, cylindrical probe head with removable immersion sleeve, overall dimensions 5/8" (15.8mm) diameter x 8" (230 mm) length | Excitation Wavelengths | 514, 532, 632, 670, 785, 830 nm, others available upon request | Spectral Range | 250 - 3900 cm-1 (Stokes)* | Working Distance | Sliding immersion sleeve provides selectable working distance to optimize measurement of clear and turbid solutions | Fiber Configuration | Permanently-aligned combination of two single fibers (100 µm excitation fiber, 200 µm collection fiber) with filtering and steering micro-optics, N.A. 0.22, with stainless-steel cabled fiber Options: Fiber sizes ranging from 50 µm to 400 µm. | Filter Efficiency | Patented design to filter laser line and quartz spectral contributions from both input and output fibers (O.D. > 8 at laser line) | Physical Resistance | Entire probe head can be heated to 200ºC.
