NSG Photometric Accuracy Calibration Standards

NSG’s nanodeposition technology overcomes the disadvantage of using solid-state neutral density filters for testing photometric accuracy compared to liquid-based filters while preserving all the advantages of solid-state neutral density filters.

NSG Precision has an elite line of photometric accuracy calibration standards that never endure material aging and therefore never have to be recalibrated.

The weakness of all other solid-state calibration standards is that they have substantial non-linearity across their surface which causes substantial expanded uncertainty. This has traditionally been a disadvantage of solid-state neutral density filters. NSG’s solid state filters are the first to overcome this deficit and provide a filter with no inconsistencies.

Liquid and solid-state neutral calibration standards are typically calibrated by the filters' manufacturers, and the corresponding filters performance certificates are supplied to customers. Whereas solid-state calibration standards 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 which is a hassle and a time-consuming and even more not practical.

Modern developments in nanotechnology have allowed NSG Precision Cells to develop state-of-the-art solid-state quantum resonance filters which render liquid filters obsolete. Through NSG, customers can benefit from substantial savings which would otherwise be spent on costly and lengthy recalibration and replacement fees for liquid filters.

NSG’s nanodeposition technology overcomes the disadvantage of using solid-state neutral density filters for testing photometric accuracy compared to liquid-based filters while preserving all the advantages of solid-state neutral density filters. Moreover, NSG’s solid-state neutral density filters for photometric accuracy allow not only for calibration at NIST wavelengths but also at ANY wavelength within the optical wavelength range of operations of our photometric accuracy neutral density filters.

So, what are some more of the benefits of using NSG's solid-state calibration standards Precision: with tolerances exceeding NIST930e standards, pinpoint accuracy is assured. Time Saving: NSG standards never have to be recalibrated due to material aging. Durability: the 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. Finally, there’s NIST compatibility and precision, which exceeds their tolerances.

Here is the current selection of NSG’s photometric accuracy calibration standards: Photometric Accuracy Calibration Standards H-F2-0.2 Filter, Photometric Accuracy Calibration Standards H-F3-0.5 Filter, Photometric Accuracy Calibration Standards H-F4-1 Filter, WAV-7 Wavelength & Photometric Accuracy Didymium Calibration Standard, and lastly, the UV/VIS Photometric Accuracy & Stray Light Calibration Kit 3.

This photometric accuracy calibration Kit 3 can test for photometric accuracy in the UV and VIS range (H-F3-0.5), Stray Light Performance in the UV and VIS range (FUV-0.5), the optical range for the H-F3-0.5 filter is 400-700nm and 200-700nm for the FUV-0.5.

Summing up, the advantages of NSG’s calibration standards are legion. First, the WAV-7 calibration standard for testing photometric accuracy is not only NIST-compliant but actually exceeds their requirements for tolerance. Secondly, the unique materiaI formation and nano-deposition proprietary manufacturing process assures unmatched stability of optical performance for calibrating photometric accuracy. NSG’s calibration standard NEVER needs to be recalibrated due to material aging. Thirdly, in addition to providing wavelengths calibration picks, NSG also supply photometric absorption data for all 5 wavelengths. Lastly, for each WAV-7 Calibration Standard NSG Precision Cells is able to provide a wavelength/absorption trace-file with 0.1 nm steps upon request.

Also, NSG Precision Cells’ WAV-7 NIST-Compliant Combined Wavelength Accuracy/Photometric Calibration Standard provides the following NIST-compliant picks' values for the wavelengths’ accuracy calibration of spectrophotometers: 329 nm, 472 nm, 512 nm, 681 nm, 875 nm. Also, it provides NIST-compliant absorbance values for the photometric accuracy calibration of spectrophotometers at the following wavelengths: 270nm, 280nm, 300nm, 320nm, 340nm.
