Sapphire crystal (Al2O3) is a sought-after material for a range of high-precision IR applications; for example, within the aerospace and aeronautical industries and in high-powered laser applications such as Er: YAG lasers. With a high transmission from 150nm up to around 5µm, not only is sapphire windows an outstanding choice for ultraviolet (UV) and visible wavelengths but it’s also an optimum substrate for applications operating within the infrared (IR) spectrum.
With excellent mechanical strength, scratch-resistance and hardness as well as an optimal thermal and chemical resistance, sapphire window is a perfect substrate choice for protective optical components, such as Windows. Furthermore, its durability means it repels attacks from harsh environments, meaning it’s suitable for a diverse variety of end applications.
Available in three options, Random Cut, Fluorescence-Free (custom-made only) and C-Cut and Z-Cut options, our sapphire window meet a range of high-precision IR requirements. Furthermore, all four types are available as custom-made components to meet a wide range of project requirements. This option allows you, as the specifier, to choose the dimensions, tolerances, shapes and coatings that are best suited to your project.
