摘要： A multilayer optical film includes a plurality of polymeric layers arranged sequentially adjacent to each other. A difference in thickness between spaced apart first and second polymeric layers in the plurality of polymeric layers is less than about 10%. Each polymeric layer that is disposed between the first and second polymeric layers has a thickness less than about 400 nm. Each layer in a group of at least three polymeric layers in the plurality of polymeric layers that are disposed between the first and second polymeric layers has a thickness greater than an average thickness of the first and second polymeric layers by about 20% to about 500%. The group of at least three polymeric layers includes at least one pair of immediately adjacent polymeric layers.

摘要： This disclosure describes co-extruded multilayer articles including at least one continuous layer and one discontinuous layer, as well as systems and techniques for the manufacture of co-extruded multilayer articles. For example, a co-extruded multilayer article is described that includes a body having a plurality of layers, where a first layer of the plurality of layers is formed from a first material and is continuous along a longitudinal axis of the body, and a second layer of the plurality of layers is formed from a second material and is discontinuously co-extruded along the longitudinal axis.

摘要： A feedblock including a first packet creator that forms a first packet including a first plurality of polymeric layers, the first plurality of layers including at least four first individual polymeric layers; and a second packet creator that forms a second packet including a second plurality of polymeric layers, the second plurality of layers including at least four second individual polymeric layers, wherein the first and second packet creators are configured such that, for each packet creator, respective individual polymeric layers of the plurality of polymeric layers are formed at approximately the same time. The feedblock may include a packet combiner that receives and combines the first and second primary packets to form a multilayer stream. In some examples, at least one of the first and second primary packets may be spread in the cross-web direction prior to being combined with one another.

摘要： An optical well is configured to receive a test sample for examining an optical characteristic of the sample at a first wavelength in a predetermined wavelength range. The optical well includes a wall having a bottom wall portion and a sidewall portion defining a chamber for receiving the test sample, and an optical film formed into a shape so that a portion of the sidewall portion includes a first portion of the optical film, and a portion of the bottom wall portion includes a second portion of the optical film. For a normally incident light, the microlayers in each of the first and second portions have an average optical reflectance of greater than about 80% in the predetermined wavelength range. The forming results in the plurality of microlayers of the integral formed optical film having a thinnest portion and a thickest portion having a thickness difference of at least 30%.

摘要： An optical system for examining an optical characteristic of a test material at at least a first wavelength includes an elongated hollow structure elongated along a length thereof and having one or more walls extending along the length of the hollow structure and defining an elongated chamber therebetween configured to receive the test material. The elongated hollow structure includes at least a first light opening, such that for the at least the first wavelength, the one or more walls have an optical reflectance of greater than about 50% for incident angles of up to at least 40 degrees, and at least one of the at least the first light opening has an optical transmittance of greater than about 50% for at least one incident angle.
