Polarizing Plate Beamsplitters
WTS polarizing plate beamsplitters are designed for narrowband beamsplitting coatings deposited on the front surface.
These optics are meant to be used at a 45° AOI. When used with normal incident, un-polarized light, the incident beam is separated into two polarized beams, p-polarized component is passed straight through, s-polarized component is reflected out at 90deg.
