    Abstract: A specular variable angle absolute reflectometer includes a light source and a mirror system in a light path of the light source. The mirror system is configured to reflect a light beam from the light source towards a sample that is optically reflective. The device also includes an elliptical roof mirror disposed in the light path after the sample having an ellipsoidal reflector surface configured to reflect the light beam back towards the sample. The device also includes a mechanism connected to the elliptical roof mirror. The mechanism is configured to rotate the elliptical roof mirror about an axis of the sample. The device also includes a detector in the light path after the elliptical roof mirror such that the detector receives light that has been reflected from the elliptical roof mirror, thence back to the sample, thence back to the mirror system, and thence to the detector.

    Abstract: A method involves determining multiple temperatures of an object from spectral data collected from the object. The spectral data covers a plurality of wavelengths. The method comprises using a computer to (a) assign an initial value for residual radiation; (b) identify a black body profile that best fits the spectral data over the plurality of wavelengths; (c) remove radiation corresponding to the identified profile from the residual radiation; and (d) return to (b) until the residual radiation reaches a termination criterion.

    Abstract: A filter comprises a support substrate. A film is disposed on the support substrate, the film comprising a polymer matrix material and a filler. The filler has a particle size distribution configured to filter a desired range of wavelengths of light, the particle size distribution having been achieved by extrusion. An extrudable composition is also disclosed. The extrudable composition comprises a polymer matrix material and a filler. The filler has an average particle size ranging from about 1 nm to about 700 nm and a concentration ranging from 0.001 weight % to 0.3 weight %, relative to the total weight of the extrudable composition.
