An intensifier tube is carried within the body for relative movement therebetween whereby the objective lens carried by the body and the intensifier tube are longitudinally adjustable relative to one another. Electrical leaf contacts, one of which is electrically connected to a battery carried by the housing body, are carried by and extend into the path of movement of the intensifier tube. The distal ends of the leaf contacts are maintained in electrical contact with electrical terminals on the end face of the intensifier tube throughout the range of relative movement between the intensifier tube and housing body.
