Sapphire rod or sapphire lift pin provide high mechanical strength combined with prevision, stable dimensional control during long term use in high temperature chemically harsh plasma environments.

According to the types of part structure, they are divided into flat rods, single convex rods, double convex rods, rotor horizontal pins, special-shaped rods, blind hole rods, ect. Synthetic sapphire with corrosion resistance ,wear resistance, thermal and chemical stability , and good optical properties. After being made into high-precision components such as stopper rods and measuring rods, they are often used in precision machinery, precision measurement and detection, and laser technology applications, such as injection plug rods, measuring rods, laser rods, laser rangefinders, laser guidance meters, gyroscopes etc, and they are widely used in environments such as corrosion resistance, wear resistance, and high thermal conductivity
