The RamanProbe IITM 
RamanProbe II是用于基于原始拉曼探头的光学元件进行浸没分析的通用光纤探头。 8“长的主体和可拆卸的套筒使探头可以直接浸入解决方案中进行的原位分析。可以选择焦距以优化黑暗或混浊溶液的测量。 标准浸入式套管由不锈钢制成，带有蓝宝石窗。 总体而言，探头的直径为5/8“，足够小，可以放置在典型的实验室规模的容器内。可以快速移除套筒，以便常规测量瓶子中的纯固体或样品。 下载（需要Adobe®Acrobat Reader）： 技术说明＃13：拉曼光纤采样探头的背景滤波 拉曼探针II规格表 特点和规格 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.
