Benefits of using Firefly's Solid-State Calibration Standards:

  • Precision- With tolerances exceeding NIST 930e standards, pinpoint accuracy is assured.
  • Save time- Firefly standards never have to be recalibrated due to materiaI aging.
  • Durability- Resilient scratch-resistant coating ensures life-time longevity.
  • Versatility- With standard 12.5x12.5mm (1cm) dimensions, they can be used in any UV-VIS spectrophotometer.
  • NIST Compatible

The FireflySci Advantage

Liquid and Solid-State Neutral Density filters are typically calibrated by the filters' manufacturers, and the corresponding filters' performance certificates are supplied to customers.  Whereas solid-state filters typically maintain their integrity for many years, the viability of liquid filters degrades much quicker due mainly to slow irreversible chemical reactions and photonic-promoted chemical reactions.Therefore, manufacturers of liquid filters typically advise customers to replace liquid filters every 1 to 3 years.

Until recently, solid-state neutral density filters had substantial non-linearity across their surface which contributed to so-called "Expanded Uncertainty"*. This was a disadvantage of solid-state neutral density filters.
 *As defined by NIST. 

Breakthrough developments in nano-technology have allowed us to develop state-of art solid-state quantum resonance filters, which are increasingly replacing liquid filters. The new Firefly solid-state filters have allowed customers to save tremendous amounts of money by removing the need to replace and recalibrated filters.

Our proprietary nano-deposition and nano-embedded technology overcomes the disadvantage of using solid-state neutral density filters over liquid-based filters while preserving all the advantages of solid-state neutral density filters. Moreover, our composite medium enables using our neutral density filters to be used for calibration not only for the NIST wavelengths but also at ANY wavelength within the optical ranges of operations of our solid-state neutral density filters.
