The Eppley Source Examination Department is equipped to determine the Spectral and Total Radiation characteristics of most laboratory and industrial sources currently in use. Color Temperature and Brightness Temperature measurements can be performed on specific sources.

  Two basic radiometric standards are available with traceability to the National Institute of Standards and Technology (NIST); the Standard of Spectral Irradiance and the Standard of Total Radiation. Eppley supplied, or customer supplied, sources can be calibrated.

  Photometric Standards are also available, calibrated in horizontal candle power.

  Please contact Eppley Laboratory for all your Standard Lamp needs.
