Abstract: An anti-reflection film (X) includes a laminated structure including a substrate (11), a hard coat layer (12), and an anti-reflection layer (13), and a luminous reflectance of the anti-reflection layer (13) side is 2% or less. A minimum value of a mandrel diameter indicating the bending resistance is in a range of 6 mm or less in a bending test according to a cylindrical mandrel method in which the test piece of the anti-reflection film (X) is bent with the anti-reflection layer (13) side inward. Additionally or alternatively, a minimum value of the mandrel diameter indicating the bending resistance is in a range of 10 mm or less in a bending test according to a cylindrical mandrel method in which the test piece of the anti-reflection film (X) is bent with the anti-reflection layer (13) side outward. Such an anti-reflection film is suitable for achieving high bending resistance together with high anti-reflective properties.

Abstract: A method of manufacturing a structurally competent, EMI-shielded IR window includes using a mathematical model that combines the Sotoodeh and Nag models to determine an optimal thickness and dopant concentration of a doped layer of GaAs or GaP. A slab of GaAs or GaP is prepared, and a doped layer of the same material having the optimal thickness and dopant concentration is applied thereto. In embodiments, the doped layer is applied by an HVPE method such as LP-HVPE, which can also provide enhanced GaAs transparency near 1 micron. The Drude model can be applied to assist in selecting an anti-reflective coating. If the model predicts that the requirements of an application cannot be met by a doped layer alone, a doped layer can be applied that exceeds the required IR transparency, and a metallic grid can be applied to improve the EMI shielding, thereby satisfying the requirements.
