◦Anti-reflection coating (AR coat) is applied to the incident and outgoing faces.
◦The dielectric multi-layer films has virtually zero light absorption and very low light intensity loss. However, transmittance and reflectance may change according to wavelength, polarization and incident angles.
◦In contrast to plate type half mirrors, cube mirrors have no ghosting or transmission optical path deviation.
