Sapphire single crystal fiber sensor has good optical transmission characteristics in visible to near-infrared band and high temperature resistance of sapphire single crystal, so sapphire fiber can be applied to near infrared laser transmission in high temperature sensing and biomedical fields.
Sapphire single crystal fiber temperature sensor has large dynamic range, high sensitivity and fast response.In addition to the advantages of anti-electromagnetic interference, it can also achieve a wide range (room temperature -2000 degrees Celsius), high precision (0.2%, 1000 degrees Celsius), high signal-to-noise ratio (1x 106dB, 1000 degrees Celsius), large broadband (10kHz) temperature measurement, and widely used in plasma deposition, high-frequency electric heating furnace and high-temperature hot gas flow and other fields.
