B&W Tek i-Raman® High Resolution TE Cooled Fiber Optic Raman System

B&W Tek i-Raman® High Resolution TE Cooled Fiber Optic Raman System

Sensitive, Versatile, Simple

  • Spectral resolution of 3.5 cm-1
  • 150 cm-1 of the Rayleigh line; 65 cm-1 option available
  • Wide Raman shift coverage
  • Patented CleanLaze® technology for laser stabilization and narrow linewidth
  • TE-Cooled 2048 pixel array
  • Fiber optic interface for convenient sampling



 The i-Raman® is part of our award-winning line of portable Ram an spectrometers. It delivers high resolution combined with field-portability, providing performance comparable to large benchtop Raman systems while only weighing less than 7 lbs. The system’s small footprint, lightweight design and low power consumption (optional battery) provide research grade Raman capabilities anywhere!The i-Raman offers 532nm and 785nm excitation wavelength standard and high resolution configurations measuring from 65 cm-1to 4000 cm-1. All i-Raman systems feature a TE-cooled CCD detector, allowing for the maximum effective integration time of several minutes. This makes the i-Raman an economical solution for many Raman applications such as teaching, product development, materials science research and quality control.
