Title: The Innovative Contributions of Jeffrey W. Hagen
Introduction
Jeffrey W. Hagen is a notable inventor based in Woodbury, MN (US). He has made significant contributions to the field of optical products, holding a total of 5 patents. His work focuses on developing advanced materials and coatings that enhance the performance of optical devices.
Latest Patents
One of Hagen's latest patents is for a textured coating for optical products. This innovative coating composition includes a first polymer and a second polymer that are incompatible and non-reactive with one another. The absolute value of the difference between the refractive index of the first polymer and the refractive index of the second polymer is about 0 to about 0.01. The first polymer and the second polymer are soluble in a carrier liquid that is a good solvent for the first polymer and a poor solvent for the second polymer. The carrier liquid is removed from the coating layer to spinodally decompose the mixture of the first polymer and the second polymer in an amount sufficient to form a substantially continuous first phase with a predominant amount of the first polymer and a substantially discontinuous second phase with a predominant amount of the second polymer. At least 70% of the second phase includes droplets with an aspect ratio, when viewed in the plane of the surface of the substrate, of less than about 3. Another significant patent is for a polarizer that includes an oriented polymeric first layer. This layer is preparable from a mixture of polyvinyl alcohol and a crosslinker, where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, ensuring high performance in optical applications.
