15 Jun 2009 Measures total hemispherical spectral reflectance, 250 to 2800 nm (most surfaces). Also available in a vacuum chamber compatible version, LPSR 300V. A unique integrating sphere instrument for easily and quickly measuring total hemispherical spectral reflectance of almost any surface. The instrument makes measurements from 250nm to 2800nm. The LPSR incorporates unique optical, mechanical, and electronic designs to provide state-of-the-art performance in a compact portable instrument. The LPSR has been designed for use both in the field for measuring the extended surfaces of operational or development hardware and for use in the laboratory on test specimens of varying sizes. The LSPR measures solar absorbance in accordance with ASTM E903. |
