Abstract
A method for making a housing that defines a cavity for a pressure sensor, the method comprising: providing a bulk of material that will form the housing; focusing a radiation beam on internal portions of the bulk of material so as to modify the internal portions, thereby defining the housing's shape, wherein upstream of the focus of the radiation beam other portions of the bulk material remain unmodified; and discarding either the modified portions or the unmodified portions of the bulk material so as to form the cavity.

A housing that defines a cavity for a pressure sensor, the housing comprising:
- a fibre-receiving hole adjacent one end of the cavity;
- and
- a diaphragm surface at the opposite end of the cavity,
- wherein the cross-sectional area of the cavity increases from the end adjacent to the fibre-receiving hole towards the diaphragm surface.
