Polarizing optical element comprising a polarizing film and method for manufacturing such element |
摘要 |
A polarizing optical element comprises a transparent optical base element and a layered structure that incorporates a polarizing film. The polarizing film is of the dichroic dye type and is oriented uniaxially. The layered structure is bonded to the optical base element by means of a layered structure that includes at least one layer of a pressure-sensitive adhesive. Thanks to the use of pressure-sensitive adhesive, the polarizing film during the bonding operation maintains a high polarization efficiency and an optical quality compatible with many applications of the optical element, especially ophthalmic applications.
