Homogeneously mixed dielectric films as double-layer antireflection coatings.
A two-layer quarter-quarter antireflection coating with a homogeneous mixture of ZnS and MgF(2) as the inner layer and MgF(2) as the outer layer was fabricated. Its transmittance was measured and found to be comparable with that of a less stable CeF(3)-MgF(2) coating. Measured peak transmittance values agree well with theoretical values.
