Raman Spectroscopy Probes
Probes and Accessories for Raman Spectroscopy Request a QuoteDownload Instrument PDFStellarNet Raman Probes are perfect for a variety of laboratory and process Raman applications.
Multiple Wavelengths such as 532, 633, 785, & 1064nm are standard “in stock” options. Custom wavelengths are usually no problem.
Easily Connectable – Connects to Raman Laser sources and Raman spectrometer detectors. Laser sources such as the Ramulaser connect via FC/APC connector and spectrometers connect via SMA905.
Raman Shift Capabilities – Raman filters for 200 cm-1 and f/2 collection optics. ContactUs@StellarNet.us for lower wavenumber shift options. Use our Raman shift calculator to easily convert from nanometers to wavenumbers!
High throughput collection – Collection optical fiber to the spectrometer is 600um core diameter providing 2-3x signal enhancement compared to typical probes. Integrated filters for laser line (with O.D. > 6) and notch filter to remove quartz spectral contributions.
Probe diameter is 4″ with 2 meter fiber length and has laser blocking switch for simple reference.
Working distance to sample is 4.5, 7.5, & 12.5mm options with field depth of +/- 1mm for penetration of sample containers Includes probe holder for solids such as pills or vials (½ inch diameter with lids) for liquids and powders.
Raman Probe Accessories
Raman-Probe-TIP – attachements tips can be purchased for additional working distance options. Just screw on to replace
Raman-Probe-TIP-Tele – Telescoping Raman probe tip lens assembly attachment for 3cm working distance. Designed to by mounted on to standard Raman probe with 5mm working distance
RPH4 – Raman Probe Holder block supports 1/2″ vials.
RPH5 – Vertical Raman Probe Holder Block for powder and solids. Samples are placed onto a slide and inserted into the measurement chamber of the block. Includes a laser safety interlock which only allows the laser to fire when the probe is securely seated into the holder.
532 Attenuator – Attenuation accessory for 532 Raman systems. Requires Part # FC-Splice. Other custom wavelengths available upon request.
