    Abstract: Light photon detecting apparatus (10) comprises a photomultiplier tube (36) in a two-part housing (14), the underside (22) of which is open. The underside (22) is fitted with an elastomeric sealing ring (28) to make an airtight and hence light-tight seal with a surface (12). Two spring-loaded part (16, 18) of the housing (14) act as a pump to produce a partial vacuum which opens a shutter (60) to expose the photomultiplier tube (36).
