Sensor window protection plate

-- with ultra-high surface hardness and chemical resistance; -- Transmittable wavelength between UVzhi and infrared; - Thinner and stronger than standard glass window sheets. Sapphire window pieces are flat polished products based on the processing of single crystal sapphire, with two parallel or wedge-shaped faces, usually used as protective Windows for electronic sensors or external environment CE detectors. Sapphire protective window piece is a special window piece used to protect the observer, the inside of the instrument and the inside of the container by using the characteristics of pressure, wear and high temperature resistance of sapphire. Single crystal sapphire window pieces are suitable for demanding applications (such as laser systems) because of their excellent surface hardness, high thermal conductivity, high dielectric permittivity, and resistance to chemical acids and bases. Because the hardness of sapphire is second only to diamond, and its structural strength is not high, so the thickness of sapphire window sheet made by strengthening the transmittance is thinner than the general high dielectric window sheet. In terms of chemistry, sapphire is a single crystal of aluminum trioxide (Al2O3), non-Chang suitable for transport between 0.2 Zhi5.5 μm. In general optical applications, the basic needs of customers can be met without coating treatment. Our products can also be coated according to customer needs, screen printing or special heat treatment, to meet the special needs of customers. Sapphire protection installed in front of the flame lights such as sensor, are placed in the oil field, mine, chemical and other inflammable and explosive easy leaking situation, but in the event of a disaster, can make the instrument unharmed, principle of personnel for the dangerous sites can obtain the real-time alarm, di low reaction disposal time effectively, protect personal Ann quan, di damage to property. Product specifications: φ28×3mm, φ28×4mm, φ28×5mm; From 52.8 x 5 mm, 76 * 5 mm; Processing index: Item index unit or standard parallelism < 20 arcseconds finish 80/50 scratch -Dig flatness is better than λ effective area transmittance range 150Nm-4.5μm uncoated
