These non-polarizing beam-splitters have a high threshold of laser-induced damage when compared to non-polarizing beam-splitter cubes. Typical cubes cause loss at around 10% due to hybrid coating absorption. The damage threshold induced by lasers is in a range around 0.3J/cm2. Beam-splitting plates that are non-polarizing are only coated with dielectric layers, which allow for a significantly higher damage threshold that exceeds 6J/cm2.
Separation of polarizations with these particular plate beam-splitters is Rs to Rp < 5%. Due to this feature, beam-splitters are ideal for use in areas with un-polarized light, or when light is of any other polarizing state. Standard items are useful for many types of lasers, due to their decent working bandwidth of a high number of nanometers.
