摘要： An optical component forming a wire grid polarizer comprising: a substrate and microchannels formed by side walls of adjacent microstructures on the substrate, the microchannels being filled with air, the microstructures being covered by a coating and the coating nearly or completely closing the microchannels to substantially separate the microchannels from the environment of the component. A method for producing such an optical component comprises the steps of: providing a substrate, providing microstructures on the substrate, wherein side walls of the microstructures form microchannels; and coating the microstructures thereby nearly or completely closing the microchannels to substantially separate the microchannels from the environment of the component.
