InPhotonics - Model RamanProbe II -Fiber Optic Probe

The standard immersion sleeve is made of stainless-steel with a sapphire window. Overall, the probe is 5/8" in diameter, small enough to fit inside typical laboratory-scale vessels. The sleeve can be quickly removed for routine measurement of neat solids or samples in bottles.

• 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. Sapphire window sealed to stainless-steel sleeve with PTFE gasket. Quartz window available as option (recommended for 633 and 670 nm excitation).
• Cable Length : 5 m std. (option: up to 200 m)
• Safety Features : Emission indicator (std.), Class I sample holders available (for use without immersion sleeve)
• Coupling System : Available with FC (std.) or SMA connectors
• Retail Price : $ 6,745 USD
