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

  • Spatial resolution—demonstrated as good as 540nm resolution on ideal sample
  • Confocal depth resolution—demonstrated as good as 1.7μm on ideal sample
  • Full spectral range of 3500-50cm-1 captured with a single exposure of the CCD avoids stitching artifacts. Extended spectral range to 6,000cm-1 available for 532nm laser
  • Supports multiple excitation lasers. 532nm, 633nm, and 780nm
