COTS Lenses

COTS Lenses are used to focus or diverge light for many defense or security applications. COTS Lenses feature a range of substrates, coatings, or a combination of the two for optimized performance in the ultraviolet, visible, or infrared. COTS Lenses may also be used to correct image aberrations. COTS Lenses are an excellent, low cost alternative to expensive custom components. Products designed for a wide range of wavelengths are available for a variety of applications’ needs.
