The RamanProbe IITM 
RamanProbe II是用于基于原始拉曼探頭的光學(xué)元件進(jìn)行浸沒分析的通用光纖探頭。 8“長(zhǎng)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(jìn)行的原位分析。可以選擇焦距以優(yōu)化黑暗或混濁溶液的測(cè)量。 標(biāo)準(zhǔn)浸入式套管由不銹鋼制成，帶有藍(lán)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(shí)驗(yàn)室規(guī)模的容器內(nèi)?？梢钥焖僖瞥淄?，以便常規(guī)測(cè)量瓶子中的純固體或樣品。 下載（需要Adobe®Acrobat Reader）： 技術(shù)說明＃13：拉曼光纖采樣探頭的背景濾波 拉曼探針I(yè)I規(guī)格表 特點(diǎn)和規(guī)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.
