45 Degree Plate Polarizing Beamsplitter, High Damage Threshold
| 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.
