Measure specular, diffuse and total solar reflectance

The 410-Solar Reflectometer conforms to ASTM E903 and C1549, the standard test methods for solar reflectance measurements. Measures reflectance at near-normal incidence for seven spectral bands. The 410-Solar specifies the specular and diffuse components of the total reflectance. Choose from eight solar irradiance functions, including air mass 0, 1, 1.5, and 2.0, to calculate total solar reflectance/absorptance.
