Half Mirror

   The single-sided dielectric multilayer film of the half mirror splits the light incident at 45‹ into transmission and reflection (ratio 50:50). The ratio of transmission and reflection varies depending on the angle of incidence. The back side is treated with an anti-reflection coating. Half-mirror Inconel has a metal coating, so the light rays that are incident at 45‹ split into transmission and reflection (ratio 30:30). If you would like to change the external dimensions or ratio, we accept special orders.
