Plane Type
Purpose Simple optical interface. Reflection, transmission and refraction are Planar Bare controlled by the refractive indices of the two adjacent layers. Simple optical interface with a single Layer Antireflection coating. Reflection, transmission and refraction are controlled by the Planar Single Layer AR refractive indices of the two adjacent layers as well as the refractive index and thickness of the dielectric coating (t_dielectric and n_dielectric). Idealised optical interface. Reflection and transmission are controlled by the critical escape angle - unity transmission for all Planar Ideal incident angles less than the critical escape angle and zero for all other incident angles. Refraction is controlled by the refractive indices of the adjacent layers. Simple specular reflector. The reflectance is specified by a constant reflectance or by a wavelengthPlanar Reflector dependent reflectance. Rays are reflected specularly. Rays are not transmitted through this plane.
