 Confocal Raman Microscopes - RAMOS E/M Series 


저희 (주)비케이인스트루먼트는 OSTEC사의 공식대리점으로 FTIR, NIR, Raman Spectroscopy 등 다양한 제품을 취급 및 공급하고 있습니다.



3D scanning laser Raman microscopes provide rapid, high sensitivity analysis 

and unprecedented convenience in use

RAMOS E/M Series Raman spectrometers are designed on the basis of research grade optical microscopes allowing the realization of the following light microscopy methods:

  • · Raman measurements
  • · Transmitted light 
  • · Reflected light (bright field and dark field illumination)
  • · Confocal microscopy
  • · Fluorescence measurements
  • · Polarization contrast and phase contrast imaging
  • · Differential interference contrast


The innovative approach to system design of Raman spectrometers ensures extremely high temperature and temporal stability of spectral measurements.

All components of RAMOS E200 system are fully integrated within an optical microscope providing compactness and mobility of the system.

In RAMOS M350, M520, M750 systems external imaging spectrographs are connected via optical fibers.

Raman measurements with the RAMOS E/M Series systems can be started in several minutes by turning a system key.

Wide spectral range, ultimate accuracy of Raman shift  measurements, high spectral resolution





Fast system configuration changing (lasers and filters switching) without additional system alignment 




Extremely sensitive detectors for Raman signal registration



  • · Spectral CCD camera provides outstanding performance due to the increased number of pixels (the number of pixels is 2048) and the smaller pixel pitches (12 x 12 μm) 
  • · Photodetector quantum efficiency is up to 95%. Low dark signal level due to two-stage thermoelectric sensor cooling
  • · Detectors operating internal memory with the capacity of up to 128 MB
  • · High-speed Ethernet interface for data transfer


The system may be completed with the following options: 

  • · Automated XY stage for an ultra wide field of scanning
  • · High temperature and vacuum cells
  • · Cryostat
  • · Remote fiber probe


High-precision spectrometer calibration

RAMOS E/M Series spectrometers can be optionally equipped with a neon lamp for high-accuracy spectral calibration



Compact confocal Raman microscope RAMOS M350 is intended for various spectral measurements with submicrometer scale image resolution. The device features high throughput and a high spectral resolution.



Confocal Raman microscope RAMOS M520 with high-end class capabilities is applicable for spectral measurements with sub micrometer scale image resolution. The device possesses all features of M350 but ensures the enhanced spectral resolution


Confocal Raman microscope RAMOS M750 is perfect for spectral measurements with the extremely high spectral resolution. Up to two detectors can be used simultaneously in the above three system models.
