Optical Probes

Spectral Products offers fiber optic probes for use in fluorescence/Raman/diffuse reflection applications (reflection probes) and absorption/transflectance applications (dip probes).

These probes offer the highest throughput in the industry. 

  • Superior design minimizes stray lights; bubbles & trapped liquid
  • Available in all industry standard terminations
  • Custom instrument / process interfaces or configurations.
  • Fixed path length or removable tip for dip probes
  • Same unit can be used for several measuring techniques
  • UV, UV/VIS and VIS/NIR versions
  • Custom configurations available

Part number Notation:

Keyword Description
