The 410-Vis-IR joins the ET100 and 410-Solar measurement heads in a single package for measuring solar reflectance/absorptance and thermal emittance. The ET100 measurement head collects directional reflectance from 1.5 to 21 μm to determine directional and total hemispherical emissivity. The 410-Solar measures reflectance at near-normal incidence from 335-2500nm. Easily switch between reflectance and emittance data collection with a single handle for data display and measurement controls.
