Acktar’s MetalVelvetTM foil was measured with the “410 Solar reflectometer” from Surface Optics Corp.
at the Industry Space Days 2018.
Solar reflection: 0.019 – 0.026 (R20°) & 0.048 – 0.102 (R 60°)
During the Industry Space Days in Noordwijk (NL) in September 2018, Acktar’s foil product MetalVelvetTM has been measured with the 410 Solar Visible / NIR portable reflectometer from Surface Optics at R 20° and R 60°.
The results show a very low solar reflectance at six sub-bands in the 0.9 – 12.0 um spectral region – see detailed measurement values below.
