North Sutton, New Hampshire (February 29, 2008) – Labsphere will be showing its complete light metrology and reflective materials and coatings product lines at the SPIE Defense and Security exhibition March 18-20 at the Orlando World Center Marriott Resort and Convention Center (Orlando, Fla.).  Of particular interest to defense and aerospace engineers will be the company’s new solutions for calibrating and testing imaging and non-imaging systems.

On display at the show will be the company’s USS-2000 20-inch Uniform Source System.  Coated with Labsphere’s proprietary highly reflective diffuse coating, Spectraflect®, the system facilitates accurate testing and calibration of electronic imaging cameras, planar arrays, photometers and spectroradiometers.  Additional Uniform Source Systems are available in a range of sizes, with various light sources, for several levels of radiance performance to suit application needs.  System calibrations are traceable to the National Institute of Standards and Technology (NIST).

To illustrate the systems’ capabilities, Labsphere’s Applications Engineering Manager, Vikrant Mahajan, will be presenting a paper entitled “Design and Characterization of uniform spectral radiance source for test and calibration of radiometers used for KOMPSAT-3.”  This look at the Korean Aerospace Research Institute’s use of Labsphere equipment for its multipurpose satellite will be presented as Paper 6958-26 of Conference 6958 on Tuesday, March 18, 2008, at 3:30 p.m.

In addition to uniform source systems, a sampling of components from across the company’s product lines will be on display.  For backlight panel displays, laser cavities and targets, Labsphere’s diffuse reflectance materials can be applied to customer-supplied parts, or complete components can be designed, fabricated, tested and calibrated to customer specifications.

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.
