వివరాలు
- The equipment enables all the optical characterisations (Transmittance, absorptance and reflectance (specular, diffuse and total)) of all sort of solar energy materials and coatings as well as all the basic characterisations of chemical compounds and the determination of their concentration. It is widely applied in solar PV, Solar thermal, optics, environment analysis and investigation of chemical and photochemical reactions.
