Web1. sep 2024 · The reflectivity of uncoated chemical vapour deposited silicon carbide is above 90% between ≈11–12.5 μm wavelengths, greater than 50% in the UV, but unsuitable for most visible applications [8]. Therefore, a high reflectivity coating tailored to the required mirror performance is usually applied on silicon carbide substrates. Webreflectivity curves all over the visible range, and they appear gray. In other words aluminum and silver reflect all the light colors illuminating them, without absorbing any. That’s why silver and aluminum are the best materials for mirrors. Silver was the only material to make mirrors in the old days, and that’s why mirrors were so expensive. WebA series of experiments are conducted in which a series of fiber Fabry–Perot cavities are constructed using uncoated, single mode glass fibers, and mirrors of varying reflectivity. The cavity length is swept, and the predictions of the model are found to be in good agreement with the experimental interferograms. premier auto body cedar city
