Premium UV-VIS Spectrophotometer Reference Standards

NSG Premium NIST Certified UV-VIS Spectrophotometer Reference Standards. NSG offers custom manufacturing of UV, VIS, and IR spectrophotometer calibration standards.

We are proud to be offering the only spectrophotometer calibration standard that can calibrate both in the UV and VIS range. Our unique FUV-0.5 calibration filter can be used for wavelengths between (200-700 nm).

NEW PRODUCT: Our unique WAV-7 wavelength calibration standard can be used for both photometric accuracy in UV wavelength range and wavelength calibration in both UV-VIS wavelength ranges. Wavelength maximum transmission/absorption values and the wavelength peaks depend on the slit-width (aka- spectral bandwidth; bandpass) of a spectrophotometer. Our trace-tables are available for 2nm spectral bandwidths and might be generated for other spectral bandwidths as a special order.
