Integrating Spheres

The uku series of integrating spheres introduces a fast and easy setup for measuring radiant power, luminous flux of light sources, and material reflection or transmission. The uls series, on the other hand, serves as a uniform light source, either controlled or fixed. The core concept of the uku series revolves around simplicity, precision, and adaptability. Its design, featuring planar surfaces, allows for the precise alignment of detectors, light sources, and material samples without the need for port adapters, ensuring exceptional flexibility at the sphere ports. Even in the standard configuration, the surface area of the ports significantly falls below 1% of the total sphere surface, exceeding the DIN 5036 standard requirements. With table-top devices offering up to 240 mm in diameter and larger models supported by a robust frame, all uku series spheres are meticulously crafted from high-quality, compact aluminum. A well-curated selection of accessories further enhances the versatility of these integrating sphere models, making it possible to achieve rapid setups and consistently reliable measurement outcomes—these are the hallmark strengths of the uku series.
