Applications
What is solar absorptance?
Solar absorptance (α) is the fraction of the incident solar energy that is absorbed by a material. It ranges from 0 to 1, where 0 indicates that no solar energy is absorbed (all is reflected or transmitted), and 1 indicates that all solar energy is absorbed (none is reflected or transmitted).
Our testing procedures
Surface Optics offers solar absorptance testing in accordance with ASTM E903 and ASTM C1549.
