Uniform Source Systems

NORTH SUTTON, N.H., Feb. 14, 2008 -- For calibration of cameras, displays, remote sensing devices, telespectroradiometers and imaging radiometers, Labsphere’s USS-800 series uniform source systems provide application flexibility and upgrade potential. Available in continuous (USS-800C) or stepped (USS-800S) output models, Labsphere’s systems perform responsivity characterization in research, quality control and process engineering settings.

USS800.jpgSystems are built on an 8-in.-diameter integrating sphere coated with Labsphere’s proprietary Spectraflect. This highly reflective diffuse coating delivers over 98-percent spatial integration. The 2-in. exit port is suitable for most portable imaging systems and arrays, with optional Spectraflect coated accessories to reduce port size as dictated by the application. A wide variety of light sources offer several levels of radiance performance; current regulated DC power supply ensures lamp consistency for reproducible results. Exit port luminance is controlled and monitored with Labsphere’s SC 6000 radiometer. USS-800 systems’ calibrations are traceable to the National Institute of Standards and Technology (NIST).

The fixed radiance output of the USS-800S is ideal for uniform illumination of devices under test or to source a nonimaging optical train, with stepped radiance outputs of 70500, 31000 or 3000 cd/m2. For greater flexibility, the USS-800C provides adjustable continuous spectral radiance and irradiance with luminance levels ranging from 0 to 9800, 13500 or 24,000 cd/m2. This configuration is most often used to characterize the linearity of nonimaging (charge-coupled device array) and imaging (camera) systems.

Labsphere’s engineering staff is available to assist in selecting system models and components.
