In-line Polarizer
|
(ILP Series)
The In-line Polarizer is designed to pass light with one specific polarization
while blocking the other polarization. It can be used to convert unpolarized
light into polarized ligth with high extinction ratio. It can also be
used to enhance the extinction ratio of signals with its excellent polarization
properties. It is ideal for high speed communication systems and test
instrumentations where high polarization extinction ratio are required.
