Solar optical materials for innovative window design

Optical Characterization of Window Materials for Aerospace Applications

An optical metrology laboratory has been developed to characterize the optical properties of optical window materials to be used for aerospace applications. Several optical measurement systems have been selected and developed to measure spectral transmittance, haze, clarity, birefringence, striae, wavefront quality, and wedge. In addition to silica based glasses, several optical lightweight pol...

Optical Studies of Materials for Spectral Design

Optical material properties have been studied in a wide wavelength range. The aim is future use of spectral design for camouflage. The main characterization techniques used in this work are Reflection Spectroscopy, Scatterometry (BRDF) and Mueller Matrix Ellipsometry. Six camouflage evaluation criteria based on reflection, emissivity, polarization, gloss, dynamic coloring and broad band propert...

Optical durability of reflector materials for solar energy applications

In line with The Paris Agreement, the world is now changing towards more sustainable options for all sorts of energy development. The solar energy sector is growing rapidly as a result of this. One area that holds great potential in changing many of the worlds heating processes, is concentrating solar power (CSP). The basic principle of CSP is to reflect incoming sunlight and concentrate it to ...
