Abstract: Various embodiments may provide an apparatus for maintaining a pressure different from atmospheric pressure. The apparatus may include a plurality of structural members coupled together to at least partially define a space which is configured to have a pressure different from atmospheric pressure, a structural member of the plurality of structural members being a support structure having an array of holes. The apparatus may also include a film covering a surface of the support structure having an array of holes. The film maybe adapted to allow a predetermined range of wavelengths of electromagnetic waves to pass through.
