Labsphere Uniform Source Systems Provide Accurate, Flexible Calibration
Continuous and stepped modules uniformly illuminate imaging and non-imaging devices for responsivity characterization
North Sutton, New Hampshire (February 11, 2008) – For calibration of cameras, displays, remote sensing devices, telespectroradiometers, and imaging radiometers, Labsphere’s USS-800 series uniform source systems provide unmatched application flexibility and upgrade potential. Available in continuous (USS-800C) or stepped (USS-800S) output models, Labsphere’s systems are a low cost solution for responsivity characterization in research, quality control and process engineering settings.
Systems are built on an eight-inch diameter integrating sphere, coated with Labsphere’s proprietary Spectraflect®. This highly reflective diffuse coating delivers exception spatial integration exceeding 98%. The two-inch exit port is suitable for most portable imaging systems and arrays, with optional Spectraflect coated accessories to reduce port size as dictated by application. A broad range 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 non-imaging 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 non-imaging (ccd array) and imaging (camera) systems.
Labsphere’s engineering staff is available to assist in selecting system models and components best suited to application needs.
