Solid colloidal optical wavelength filter
The present invention relates generally to techniques and methods to filter optical wavelengths for spectroscopy, protection from intense radiation, monochromatizing, and analyzing optical radiation, and more particularly to a solid colloidal rejection filter and a method for constructing a solid colloidal rejection filter. A solid colloidal optical wavelength filter includes a suspension of spherical particles dispersed in a coagulable medium such as a setting plastic. The filter is formed by suspending spherical particles in a coagulable medium; agitating the particles and coagulable medium to produce an emulsion of particles suspended in the coagulable medium; and allowing the coagulable medium and suspended emulsion of particles to cool. 3 figs.
