• Infrared grade sapphire substrate • Quality infrared coating • Optimized in near-infrared to middle infrared • Main application wavebands: 2.0 to 2.7 microns, 3 microns to 5 microns Sapphire has many applications in the first and second atmospheric windows (2.0 to 2.7 microns and 3.0 to 5.0 microns) of mid-wave infrared. Infrared sapphire windows are combined with MWIR (Mid-wave infrared) coatings to meet different application requirements. Technical requirements of substrates for infrared sapphire window. For the sapphire window applied to mid-wave infrared, Creator Optics selected infrared grade sapphire single crystal (Al2O3) as the substrate. Their average transmittance in mid-wave infrared is more than 87%. These infrared grade sapphire crystals are processed into the required precision outer size infrared sapphire window blank by laser orientation machines, CNC cutting machines, cylindrical mills, multi-wire cutting machines, etc. They are then processed by deep CMP, MRF to complete an infrared sapphire optical window with excellent surface quality, surface flatness. Optical coatings of infrared sapphire windows. The coating of infrared sapphire windows used for MWIR applications is usually the antireflective coating and related functional film in these wavebands, such as hard protective film, hydrophobic and oleophobic film, etc. They need to be optimized for specific application wavebands. Hydrophobic and oleophobic film How to guarantee the performance of infrared sapphire windows. All infrared sapphire windows provided by Creator Optics are strictly inspected.
