the flexible integrating sphere series uku / uls

uku series integrating spheres enable the fast and easy setup for measurements of the radiant power and the luminous flux of light sources as well as the reflection and transmission of materials.
All types of the uku series are available as "uls" version (uniform light source). These spheres come with one or several light sources, controlled or with fixed light source.
The idea is simple, exact and flexible. The uku series concept is based on planar surfaces with concentric positioning circles allowing to adjust any type of detector, light source and material sample easily and without port adapters in a highly flexible way to the integrating sphere ports. The total area of the port openings in the standard version is significantly less than 1% of the total sphere area and thus complies with DIN 5036. Up to a diameter of 240 mm, the models of the uku series are designed as tabletop systems. Larger diameters are held in a stable frame.

Integrating sphere series uku

All types are made of high-quality compact aluminum. A well-stocked selection of accessories is available for the most flexible use possible for the various applications. Fast set-ups with trustworthy measurement results, these are the strengths of the uku series.

  • Robust integrating sphere made of aluminum
  • Solid welded construction in cantilever aluminum frame
  • Interior coating of high-quality barium sulphate
  • External coating RAL9005 (deep black), other coating possible on request
  • Hinged hemisphere
  • Ergonomically designed working height (table-top device)
  • Sample holder in the center of the sphere (optional)
  • Sample holder at the side port (optional)
