Curable composition and optical element comprising cured product thereof

An apparatus for converting gas using gliding plasma. The apparatus includes: a reaction chamber; an electrode member inside the reaction chamber and insulated from the reaction chamber; a power source applying electricity to the reaction chamber and the electrode member; a magnetic field generating unit installed outside the reaction chamber to rotate plasma induced inside the reaction chamber in a circumferential direction of the electrode member for forming a plasma region; and a gas supplying unit supplying material gas into the reaction chamber to allow the material gas to pass through the plasma region for converting the material gas into a different gas by energy received from the plasma. In the gas conversion apparatus, the plasma region can be widely formed in the reaction chamber to increase gas conversion rate.
