Photometric Accuracy & Absorbance Calibration
Save thousands of dollars a year by using our solid-state photometric accuracy verification and wavelength calibration standards. Our filters are NIST traceable reference standards that maintain their photometric stability for years.
Please review our main calibration page for all of our unique advantages.
FUV Series: UV/VIS Photometric Accuracy Calibration Standards (200-700nm) (Optical Densities: 0.04 - 4.0au)
FUV Series: UV/VIS Photometric Accuracy Calibration Standards (200-700nm) (Optical Densities: 0.04 - 4.0au)
Firefly's FUV neutral density solid-state filter series tests photometric accuracy in the UV and VIS range from 200-700nm. Our solid-state nano-deposition technology produces unparalleled stability and keeps the filter in spec for years.
