Have confidence in every Lamp and Luminaire you measure in a Labsphere illumia®Plus light measurement system. Uncertainty is inherent in every measurement. To better understand the value of a measurement, analyzing the uncertainty is required and instills confidence in the measured values.
Labsphere is a recognized leader in the field of light metrology. Let us analyze the uncertainty of your lamps and luminaires in a Labsphere total spectral flux light measurement system.
For each Lamp or Luminaire, a Labsphere Uncertainty Analysis Report Provides
Type A and Type B Uncertainty Contributions including:
- Reference lamp standard spectral flux uncertainty1
- Current to the reference lamp(s)
- Aging of the reference lamps
- Wavelength accuracy of the spectrometer
- Noise contributions
- Stray light Near field absorption
- Sphere uniformity response
- Non-linearity
- Temperature
- Combined uncertainties
- Degrees of freedom for each contribution factor
- Expanded uncertainty
- Spectral flux uncertainty every 5nm
1Included with Labsphere’s ISO/IEC 17025 NVLAP Lab Code 200951-0 Accredited Lamp Standards
