Overview: Plate beamsplitter is the most common type of beamsplitter which
reflects and transmit light at 45° angle. Our 45
Deg Polarizing plate beamsplitter separates the input beam
into two orthogonal components such as P-polarized light, which is
transmitted while S-polarized light is reflected at a 45°angle. Plate beamsplitter has different benefits over cube beamsplitters
such as high tolerance over advanced levels of power without any
mutilation and it is designed without optical adhesive for higher
energy absorption. And unlike traditional polarizing beamsplitters, which are designed
for use at Brewster's angle, these 45 degree Polarizing plate
beamsplitters are apparently meant to be used at a 45° AOI, which
allows for easier mounting. It is commonly used in applications like laser, imaging, or life
science due to its variety of configurations.
