Brewster's Angle Sample Holder

Our Brewster’s Angle Sample Holder allows thin films to be measured at various angles using transmission spectroscopy. Such measurements are used to extract film thickness and refractive index data from the resulting interference fringes.

The Brewster's Angle Sample Holder also eliminates the interference fringes which often obscure weak absorption bands. When used with a polarizer and positioned at Brewster’s angle, p-polarization light is transmitted through a surface with minimal reflection.
