Confocal Raman

Home/Confocal Raman

With Sixty years of experience in spectroscopy and using the most advanced technology, JASCO offers the best solutions for micro-Raman analysis with a complete range of micro-Raman systems.

Raman spectroscopy is capable of measuring impossible small site in the infrared microscope. Raman spectroscopy with such features is becoming popular as a general-purpose analytical instruments, but micro-Raman spectrophotometer traditional took skill optimization of measurement conditions, optical adjustment and data analysis. The NRS series will change the way Raman is used for many different applications.

All NRS Series Raman instruments include a color CCD sample viewing system with image capture capability. Utilizing the same basic optical system, JASCO designed a family of micro-Raman spectrometers that offer a range of capabilities from simple, single laser, single grating instruments to advanced research grade systems with low wave number measurement, wavelength extension from the deep UV to NIR, and the ability to use or add up to six lasers.

A range of micro Raman models are available:

RMP-500 series Portable Raman Spectrometer


Probe Raman Spectrometer

Probe Raman Spectrometer

The JASCO RMP-500 Series Versatile Laser Raman spectrometer system incorporates a fiber optic probe with a small X-Y-Z stage, compact laser, a high-throughput spectrograph and Peltier-cooled CCD detector. No special utilities, such as coolants, are required allowing the system to be used almost anywhere in the field or in a laboratory. The flexibility of optical fiber coupling enables remote measurements by locating the probe right at the sample. The fiber optic probe features an integrated CCD video camera for sample positioning and capturing of digital sample images. All operations are performed by the dedicated software package based on JASCO Spectra Manager II™.

The RMP-500 Series consists of three models, the RMP-510, 520 and 530, ranging from small, portable units suitable for in-situ measurements to research-grade systems to provide capabilities for a wide range of application requirements. The RMP-500 system is controlled using Spectra Manager II™, JASCO’s powerful Windows-based cross-platform spectroscopy software package. The system is capable of both laboratory work and on-site measurements in the fields of process control, QC, forensics, art conservation and mineralogy.

RFT-6000 FT Raman Spectrometer

The JASCO RFT-6000 F-Raman model is a module that is coupled to the FTIR-6800 spectrometer which allows obtaining both the IR spectrum and the RAMAN. Unlike the dispersive Raman where LASERs are normally used in the visible range, FT-Raman spectroscopy virtually eliminates the fluorescence of the sample itself or the impurities in the sample when irradiating with a 1064nm LASER. Likewise it allows the irradiation of the sample without risk of its degradation.

Regarding sensitivity, the InGaAs detector is much more stable and less sensitive to thermal variations than the most common Ge detector. In addition, the gold-coated optical surfaces of the FTIR 6800 allow maximizing the sensitivity since gold’s reflectivity is far superior to that of aluminum. Finally, the ability to add successive scans for the Fourier transform technique compensates for the loss of sensitivity inherent to weak Raman signals. The gold-coated optical surfaces of the FTIR 6800 maximize the sensitivity of the technique.

System Features

  • Air cooled laser
  • Laser safety interlock system
  • IR and Raman spectra can be measured using the same hardware
  • Easy switching to and from Micro mode (optional)
  • Optional mapping for Micro mode
  • Horizontal sample stage for simple sampling
