Abstract
A two-layer quarter-quarter antireflection coating with a homogeneous mixture of ZnS and MgF2 as the inner layer and MgF2 as the outer layer was fabricated. Its transmittance was measured and found to be comparable with that of a less stable CeF3–MgF2 coating. Measured peak transmittance values agree well with theoretical values.Keywords
