Highest diffuse reflectance material with most Lambertian properties

North Sutton, New Hampshire (Feb. 28, 2013) – Labsphere products have met NVLAP ISO 17025 technical competence and management system requirements that demonstrate its ability to routinely deliver technically valid test results and calibrations. Labsphere’s chemically inert standards offer the highest diffuse reflectance values of any known substance.

Labsphere has received accreditation for its Spectralon® Diffuse Reflectance Standards and Targets as an NVLAP ISO 17025 calibration laboratory. Previously, Labsphere earned accreditation as an NVLAP Lab 200951-0 for calibrated Spectral Flux Lamp Standards and Calibrated Forward Spectral Flux Standards. All were the result of rigorous on-site assessments and technical evaluations of the company’s engineering, manufacturing and calibration departments. The National Institute of Standards and Technology governs the National Voluntary Laboratory Accreditation Program (NVLAP).

Spectralon Standards and Targets offer the highest diffuse reflectance values of any known substance and are available in gray, white and various colors. Durable, chemically inert Spectralon is spectrally flat over the UV-VIS-NIR spectrum. It is optically flat to +/- 4 percent over the range of 250 - 2500 nm and +/- 1 percent over the photopic region of the spectrum. Spectralon Diffuse Reflectance Standards and Targets are the most Lambertian reflectors available for use over the wavelength range from 250 - 2500 nm.

NVLAP accreditation signifies that Labsphere operates in accordance with stringent guidelines pertaining to quality systems, engineering expertise, technical personnel, test and calibration methods, laboratory equipment and environment, measurement traceability, handling of test and calibration items and accuracy in test and calibration reports.
