Abstract
An optical filtering/electromagnetic screening structure for being joined to at least one transparent substrate, especially made of glass. The structure includes at least two plastic sheets and including, or intended to be joined to the sheets, a conducting electromagnetic screening element. At least one sheet is made of a thermoplastic, the other sheet constitutes a sheet for covering the conducting element or the thermoplastic sheet, and either one or both of the two sheets incorporate at least one mineral pigment or at least one organic dye to produce, in respect of the structure, an orange filter for light of wavelength centered on 590 nm.
Claims20
An optical filtering/electromagnetic screening structure to be joined to at least one transparent substrate, the structure comprising:
- at least first and second plastic sheets;
- and
- a conducting electromagnetic screening element between the first and second plastic sheets,
- wherein at least one of the first and second sheets is made of a thermoplastic, the other of the first and second sheets constitutes a covering sheet for covering the conducting element or the thermoplastic sheet, and
- wherein one of the first and second sheets is neutral to light while the other of the first and second sheets includes at least two pigments or dyes that provide an orange filter and an infrared filter, respectively, the orange filter filtering out light having a wavelength centered on 590 nm.
