Variable constant colour temperature luminance source

ULS300 from Bentham

The ULS300 is designed for applications requiring a variable, yet constant colour temperature (CCT), luminance source. Comprising a stable 250W quartz tungsten halogen lamp (QTH), light is transported to a 300mm diameter integrating sphere via an eight branch fibre for homogeneous illumination.

Features
  • Sphere with 100mm aperture, 50mm port reducer used to increase the radiance
  • Luminance continuously variable from <30 cd•m-2 to 14500 cd•m-2
  • CCT 3100K ±20K variation over full luminance range
  • Light transported via an 8-branch fibre for homogenous illumination
  • Features 250W quartz halogen (QTH) lamp

Further information

Continuously variable from <30 cd•m-2 to 14500 cd•m-2 the ULS300 output is highly-uniform over the 100mm diameter aperture, ±0.05% independent of luminance setting. The CCT is nominally 3100K with less than ±20K variation over full luminance range.

Micrometer adjustable bi-lateral slits situated between the lamp and the fibres allow for high-accuracy light level adjustment over 50μm to 10mm.

Core benefits

  • Supreme uniformity and high stability across a wide range
  • Delivers continuously variable luminance
  • Measure with confidence, calibration performed with respect to Physikalisch-Technische Bundesanstalt (PTB, Germany)
  • Exceptional uniformity ±0.05% over 100mm diameter aperture, independent of luminance setting
