Portable Emissometer & Solar Reflectometer
410-Vis-IR - Surface Optics Corporation
The 410 Vis-IR has been developed as a modern replacement for the classic Gier Dunkle DB100 reflectometer. The 410 Vis-IR measures total reflectance at combined 13 spectral bands. The Vis head operates from 335 nm to 2500 nm, and the IR head operates from 1.5 microns to far IR. The reflectances in the bands are converted to spectral information. Solar irradiance function or blackbody function is applied to calculate solar absorptance or thermal emissivity for two angles 20 and 60 degrees. Hemispherical total emissivity is predicted based on calculated directional emissivity.
