Multilayer Optical Film - A simplified explanation of the abstract
This abstract first appeared for US patent application 18560172 titled 'Multilayer Optical Film
The multilayer optical film described in the patent application consists of several polymeric layers that allow at least 30% transmission of normally incident light with a specific wavelength and polarization direction.
- Each polymeric layer is less than 500 nm thick.
- The film includes first, second, and third polymeric layers with different refractive indices and thicknesses, arranged sequentially.
- The film's design ensures that the product of the refractive index and thickness of the second layer falls within a certain range relative to the product of the first and third layers.

Original Abstract Submitted
A multilayer optical film includes a plurality of polymeric layers transmitting at least 30% of a substantially normally incident light having a first wavelength and polarized along an in-plane first direction of the polymeric layers. Each of the polymeric layers has an average thickness of less than about 500 nm. First, second and third polymeric layers in the plurality of polymeric layers are disposed sequentially adjacent to each other and have respective indices of refraction n1, n2 and n3 along the first direction at the first wavelength and respective average thicknesses d1, d2 and d3. n2d2 can be within about 40% of m(n1d1+n3d3), where m is a positive integer.
