Details
The equipment enables optical and thermal emittance characteristics (Transmittance, spectral emittance and thermal emissivity) of solar absorber materials and coatings especially employed in the field of solar thermal applications. Also, it enables all the basic characterisations of chemical compounds in the form of solids, liquids and low temperature crystalline in the IR region. It is widely applied in solar thermal, Solar PV and chemical analysis.
- Integrating sphere (To determine the spectral emittance of opaque thin films)
- High pressure cell with Blackbody attached to temperature controllers (To determine the radiative emission of thin films at temperatures from 100 °C to 800 °C)
- Transmittance mode (To determine the functional groups in a thin film or pellet)
