An optical sensor is disclosed for measuring pressure and/or temperature. The optical sensor is adapted for use in high temperature environments, such as gas turbines and other engines. The optical sensor comprises an optical assembly having a sensor element, a spacer and a lens arranged along the optical axis. The sensor element is spaced from the lens by the spacer. An optical fibre is coupled to the optical assembly for illuminating the sensor element. The optical assembly is resiliently mounted in a housing such that the optical assembly is insulated from shock to the housing. There is also disclosed a method of assembling the optical sensor.
