摘要：A solid state form of a dye-solution absorption filter is disclosed. Physical vapordepositable (i.e., evaporable) dyes are codeposited with a polyester matrix in a vacuumsystem to randomly disperse dye molecules in a solid dilutant. The dyes are selected toabsorb at the wavelengths of interest. Dilution in a transparent matrix affords narrowband absorption and good out of band transmittance. Multilayer configurations allowabsorption of a plurality of wavelengths. The filter coating conforms to curved andsharply contoured surfaces and layers only 10 microns thick afford very highabsorptance.
