Radiation standards with spectrally resolved or spectrally integral calibration allow the tracing back of measuring instruments or other radiators to national and international standards.
Low calibration uncertainty
With respect to NIST calibrations have basic uncertainties of 1% in the visible range, 2.5% in UV (with 250nm) and 3% in IR (with 2000nm). Furthermore, there is the uncertainty with respect to the calibration of the sampling points for the specific calibration lamps. Sometimes, a calibration uncertainty of +/- 0.5% only can be ensured.

Discharge lamps - Incandescent lamps - IR Glower - LED-Standards
Calibration standards are available for the spectral range of 200nm to 30µm and being realised based onto different principles of generation of radiation:
- UV Deuterium discharge lamps
- UV-IR Incandescent lamps
- IR-FIR Ceramic glowing radiator or blackbody temperature radiator
- VIS-NIR LED-light sources
