USS-800 Labsphere series

Share this on social media:

Labsphere has released its USS-800 series uniform source systems for the calibration of cameras, displays, remote sensing devices, telespectrometers and imaging radiometers.

Available in continuous (USS-800C) or stepped (USS-800S) output models; Labsphere’s systems are built on an eight-inch diameter integrating sphere, coated with Labsphere’s proprietary Spectraflect. This highly reflective diffuse coating delivers spatial integration exceeding 98 per cent.

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 70,500, 31,000, or 3,000 cd/m2.

The USS-800C provides adjustable continuous spectral radiance and irradiance with luminance levels ranging from 0 to 9,800, 13,500, or 24,000 cd/m2. This configuration is most often used to characterise the linearity of non-imaging (ccd array) and imaging (camera) systems.
