See Available Options

Precision Cells' FUV neutral density solid-state filter series tests photometric accuracy AND stray light performance in both the UV and VIS ranges.
All Precision Cells calibration standards are NIST traceable and NIST performance-compliant. Performance of all Precision Cells reference calibration standards, including but not limited to this standard, meet or exceed NIST requirements.

Unless recalibrations on a periodic basis are required by QA procedures of a customer's organization, all Precision Cells solid-state calibration standards do not need to be recalibrated due to material aging.

Where required, Precision Cells will provide periodic recalibrations. Contact us for more information.

Photometric Liquid Standards
Stray Light Liquid Standards

  • Photometric accuracy in the UV and VIS range
  • Stray light performance in the UV and VIS range (with matching HF Series filter)

Product specs:

  • Optical densities: 0.04au, 0.2au, 0.3au, 0.5au, 0.7au, 1.0au, 1.5au, 2.0au, 2.5au, 3.0au
  • Expanded uncertainties: FUV-0.04 (+/- 0.0019au), FUV-0.2 (+/- 0.0022au), FUV-0.3 (+/- 0.0020au), FUV-0.5 (+/- 0.0022au), FUV-0.7 (+/- 0.0023au), FUV-1.0 (+/- 0.0042au), FUV-1.5 (+/- 0.0054au), FUV-2.0 (+/- 0.0055au), FUV-2.5 (+/- 0.0090au), FUV-3.0 (+/- 0.0181au).
  • Wavelength range: 200-700nm. Standard peaks included on certificate of calibration are 250, 280, 340, 360, 400, 465, 500, 546.1, 590 and 635nm. Precision Cells can provide alternate peaks in the 200-700nm range upon request.
  • External Dimensions: 12.5 x 12.5 x 45 mm

Benefits of using the FUV Photometric/Stray Light Accuracy Filters:

  • Highly accurate and consistent spectrophotometer calibration every time
  • Never has to be replaced
  • Never has to be recalibrated if used properly
  • Scratch-resistant coating protects optical surfaces
  • Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45mm holder)
  • Surpasses NIST-2031a requirements and tolerances
  • Full NIST traceability and compliance
Included with FUV filters:
  • Instruction manual
  • Certificate of calibration with NIST traceability
  • Photometric data tables are available for qualified customers. Please contact us for more information.
All of our calibration standards are proudly made in North America

The pricing below is for FUV filters that require a corresponding HF filter for stray light calibrations. For FUV filters that can do both photometric accuracy and stray light, please see the link below.

Product Comments & Ratings


These standards have worked well for us and are very durable. Customer service is easy to reach and knowledgeable. They have been able to address our needs specifically.

by Qi Lin

Our company uses FUV-0.5 for the performance check of UV Spectrometers, because FUV-0.5 is very easy to handle, and no re-calibration is needed.

by Gloria Lee

This is the first time our company has purchased and used a solid-state calibration standard for our instruments. The procedure is straight forward, works perfectly as expected and is a lot easier than using liquid standards. The best part about using this solid-state calibration standard is that we no longer have to worry about an expiration date for our calibration standard. Currently, we only need verification at one wavelength, but this standard will continue to be useful in the case that we expand the scoop of our procedures.
