2π PLANCKIAN EMITTER

Integrating sphere calibration with 2π radiant flux

This lamp has been developped to serve integrating sphere calibration when using the 2π-port. The intensity profile of the lamp is close to a lambertion distribution, thus creating a homogeneous illumination of integrating spheres already within the first irradiance.

Sphere-photometer or sphere-spectradiometer calibration is assured by certificates for both luminous or radiant flux.

Features

  • 2π emission with lambertian profile
  • Emission aperture is adapted to fit LMT’s 2π-ports in integrating spheres
  • Input power 4.2 A DC, 50W
