  • Publication number: 20200271838
    Abstract: An optical device can comprise a subassembly with at least two different optical components in a stack. Each optical component can be a wavelength filter, a polarizer, or a waveplate. This stack can be a subassembly which can be manufactured separately from other components like CCD, CMOS, liquid crystal layer, electronic components, and electrodes. Consequently, this subassembly can be manufactured relatively inexpensively and with large variety of configurations. After first manufacturing the subassembly, it can then be attached to other components (e.g. CCD, CMOS, liquid crystal layer, electronic components, electrodes, etc.) to form the completed device (e.g. optical display, radiation detection, radiation measurement, imaging, etc.).
