'''Brewster's angle''' (also known as the '''polarization angle''') is an [[angle of incidence (optics)|angle of incidence]] at which [[light]] with a particular [[Polarization (waves)|polarization]] is perfectly transmitted through a transparent [[dielectric]] surface, with ''no [[Reflection (physics)|reflection]]''. When ''unpolarized'' light is incident at this angle, the light that is reflected from the surface is therefore perfectly polarized. The angle is named after the Scottish physicist [[David Brewster|Sir David Brewster]] (1781–1868).<ref>{{Cite journal |last=Brewster |first=David |date=1815 |title=On the laws which regulate the polarisation of light by reflexion from transparent bodies |url=https://books.google.com/books?id=U-U_AAAAYAAJ&pg=PA125 |journal=Philosophical Transactions of the Royal Society of London |volume=105 |pages=125–159 |doi=10.1098/rstl.1815.0010 |doi-access=|url-access=subscription }}</ref><ref>{{Cite journal |last=Lakhtakia |first=Akhlesh |date=June 1989 |title=Would Brewster recognize today's Brewster angle? |url=http://www.esm.psu.edu/~axl4/lakhtakia/Documents/No087(ON).pdf |journal=Optics News |volume=15 |issue=6 |pages=14–18 |doi=10.1364/ON.15.6.000014}}</ref>
