Single wavelength, Non-polarizing plate beamsplitter
These non-polarizing plate beamsplitters are coated so that the s and p components coincide in reflectance at the wavelength of interest. This means that they will not change the state of polarization of the incident beam. They are anti-reflection coated for the same wavelength on the back face.
