Raman Probes

We’ve designed our own high NA Raman fiber optic probes to be perfectly matched to our f/1.3 Raman spectrometers. This ensures the field of view of the spectrometer is completely filled by light from the probe, vastly improving collection efficiency and signal over other Raman probes available on the market.

 

Excitation Wavelength 405, 532, 633, 785, 830, or 1064 nm
Collection Optics f/1.3
Collection Area 1 mm diameter spot when using 600 µm collection fiber
Collection Distance 11 mm (lens to sample)
Laser Band Pass Filter 3 nm bandwidth, >OD 6 out of band rejection
Long pass/Edge Filter >80% transmission, laser line blocking >OD 6
Excitation & Collection Fibers Included

 

High OD rejection filters eliminate laser sidebands and autofluorescence generated within the collection fiber for the cleanest signal possible. The compact stainless steel probe head mates to laser and spectrometer with replaceable optical fibers. Excitation and collection fibers matched in NA to the probe head and spectrometer are included to optimize signal and reduce data acquisition time.
