FUV 0.5 Unique Combined UV/VIS Light Photometric Accuracy & Stray Light Calibration Standard
FUV - 0.5 Unique Quantum Resonance Nano-Deposition Neutral Density Solid-State filter for testing stray light performance and the Photometric Accuracy of spectrophotometers in both UV and VIS ranges. Optical density = 0.5
Made in North America.
Benefits of using FUV - 0.5 Solid-State Calibration Stray Light/Photometric Accuracy Filter:
The FUV - 0.5 calibration filter can test the following:
- Highly accurate and consistent spectrophotometer calibration every time
- Never have to be replaced
- Save recalibration time, this filter never has to be recalibrated if used properly
- Easy to handle due to scratch resistant coating
- Can be used in any spectrophotometer
- Standard 12.5 x 12.5 x 45 mm dimensions
- Meets or exceeds NIST-930e requirements
- NIST Compatible
The FUV - 0.5 calibration filter can test the following:
- Photometric Accuracy - In the UV and VIS range
- Stray Light Performance of Spectrophotometers - in the UV and VIS ranges (Note: If a user does not have any existing calibration standards liquid or solid based with an optical density of 0.5 mm, Photometric Filter H-F3-0.5 is also required.
Liquid and Solid-State Neutral Density filters for testing photometric accuracy of spectrophotometers are typically calibrated by the filters' manufacturers, and the corresponding filters performance certificates are supplied to customers. Whereas solid-state filters typically maintain their performance for many years, performance of liquid filters degrades much quicker due to so-called slow irreversible chemical reactions, photonic-promoted chemical reactions, and certain other reasons.Therefore, manufacturers of liquid filters typically request customers to replace liquid filters every 1 to 3 years.
At the same time, until recently solid-state neutral density filters had substantial non-linearity across their surface which caused substantial contribution to so-called "Expanded Uncertainty"*. This was a disadvantage of solid-state neutral density filters.
*As defined by NIST.
Modern development of nano-technology allowed us to develop state-of art solid-state quantum resonance filters towards replacing liquid filters, such that customers can benefit from substantial savings on filters' replacements.
Our proprietary nano-deposition and nano-embedded technology overcomes the said disadvantage of using solid-state neutral density filters comparably to liquid-based filters while preserving all the advantages of solid-state neutral density filters. Moreover, our composite medium allows using our solid-state neutral density filters for calibration and research and development purposes of our customers not only for the NIST wavelengths but also at ANY wavelength within the optical wavelength range of operations of our solid-state neutral density filters.
The optical wavelength range of operations of our FUV-0.5 Stray Light/Photometric Accuracy Filter is 200-700 nm. Photometric data tables are available for qualified customers. Please contact us for more information.
The instruction on how to use our FUV-0.5 product for testing stray light performance of spectrophotometers is included with the every sold FUV-0.5 filter.
