Solar Spectrum Uniform Source

Labsphere has released a new product that allows users to generate a uniform radiance field simulating the spectral shape of solar light. The Solar Spectrum Uniform Source system can be used in applications requiring the replication of sunlight and daylight conditions.

The product has been designed for Lambertian solar simulation testing of high speed video and film systems, space-based imaging systems, and single element broadband sensors. It could also be used to detect the dynamic range, linearity and uniformity of focal plane arrays.

The Solar Spectrum Uniform Source duplicates the spectral shape of solar radiation with xenon and tungsten halogen sources and an integrating sphere. The system is capable of approximating the spectral radiance of a one hundred percent albedo source, or the spectral curve of the ASTM Standard D65.

The source can also approximate near blackbody spectrums with colour temperature ranges from 3000 K to 6000 K. The system includes a photopic detector for luminance monitoring, a high-dynamic range, low-noise CCD-based spectrometer to monitor spectral irradiance from 350 nm to 1050nm, spectrometer and uniform source control software, and multiple detector options. It is available in two models to meet customer output radiance and illumination area requirements.
