Stray Light Calibration
NSG's FUV neutral density filters not only calibrate for photometric accuracy but also stray light in the UV and VIS range. With one FUV filter you can replace multiple liquid-based stray light verification filters and save thousands:
Researchers can easily spend over $3,000 on liquid stray-light filters, but the FUV series photometric/stray light filter costs a fraction of this amount. NSG sells these filter for a very low price because our unique technology allows making these filters extremely precise while still being cost effective. We want to ensure that researchers have access to the finest calibration standards available on the market today.
One of NSG's FUV filters can be used to verify stray light performance in both the the UV and VIS range. This filter replaces over 12 liquid-based stray light filters of leading manufacturers, which allows customers the benefit of saving thousands of dollars on purchasing and recalibrating liquid stray light filters.
In the event QA procedures require usage of liquid stray light standards, NSG offers these traditional standards as well.
NSG's FUV stray light/photometric accuracy neutral density filters and NSG liquid calibration standards are NIST Compliant and NIST Traceable.
NSG provides a Unique Lifetime Warranty for all our calibrations standards.
