  • Optional, automated polarized Raman capabilities provide structural information that complements chemical information
  • Add new wavelengths without tools or service engineer visit

Laser Safety

  • Microscope independently certified as class-1 laser safe. (Note: Optional fiber-optic accessory and some other optional accessories are class IIIb laser devices requiring laser safety precautions and laser safety eyewear.)
  • Laser is physically blocked from visual viewing path to prevent exposure to the eyes while viewing.


  • Complete package for DQ/IQ/OQ/PQ validation is available including extensive documentation and automated software protocols
  • Omnic D/S software offers CFR 21 part 11 compliance

Exceptional Performance
