COTS Filters and Polarizers are used to transmit certain wavelengths or polarization states of light for a range of defense or security applications. COTS Filters are designed to transmit a certain wavelength or wavelengths while reflecting unwanted wavelengths. COTS Polarizers transmit only specific polarizations of light. COTS Filters and Polarizers are an easier, low cost alternative to developing similar custom components. Products designed for different wavelengths or polarizations are available to suit many applications’ needs.
