XperRF Raman System

High-end confocal Raman Spectroscopy Imaging System with FLIm Capability

Description:

This desktop high performance Raman spectroscopy system, is designed to deliver high performance, flexibility and ease of use. The XperRF includes fast, wide area 2D scanning, confocal/3D Raman imaging and analysis, and a range of lasers and gratings.  Photoluminescence and Electroluminescence.

This instrument is a complete laboratory spectroscopy system with a modular design such that the system can be expanded later as research develops and budgets allow.

Included as standard

  • Confocal 3D imaging and analysis
  • Fast 2D scanning
  • Bright field microscopic imaging
  • Up to three laser/filter selections
