Polarization:
In general, at angles greater than fifteen degrees, coated or uncoated pellicles will transmit more P polarized light than S polarized light: the coated or uncoated pellicle will reflect more S polarized light; than P polarized light. Pellicles, with or without coatings, can be manufactured to meet specifications for a given state of polarization.

Interference Effects:
Sinusoidal thin film interference effects are shown on the transmission scans on this page. These effects can be used to maximize the transmission or reflection of the pellicle for specific wavelengths and incident angles.
