FSS99 enjoys an excellent and well-deserved reputation as a durable, high reflecting coating for ground based and space flight applications. Originally there was only one FSS99, designed for visible reflectance, primarily on glass substrates. In recent years customer demand has led us to offer multiple versions – the FSS99 Family – in which the design is optimized for different spectral requirements. Peak reflectance can be set anywhere in the visible or NIR, and the layer structure can also be optimized for a variety of different substrate materials. When ordering, please specify peak wavelength of interest.
