◦Half mirror divides input beam into reflectance and transmittance at a 1:1 ratio. A beamsplitter with R:T (1:1 ratio) is called “Half Mirror”.
◦Four surfaces of the cube are coated with multi-layer anti-reflection coatings.
◦The loss of input beam is minimized as there is no absorption from dielectric coating. However the reflection to transmission ratio of these dielectric cube half mirrors vary depending on wavelength, polarization and the incident angle of input beam.
