APPLICATION NOTES
|
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. |
