    • A military projector comprises a tubular housing that contains a high intensity lamp, a reflecting mirror behind the high intensity lamp, a negative lens which is carried in a first mounting member located in front of the lamp, and a pair of positive meniscus lenses which axe mounted in a second mounting member spaced from and movable relative to the negative lens so that the distance between the negative and positive lenses can be varied. A carrier member having a clear opening and an opening containing a filter is located between the negative and positive lenses. A moving means moves the carrier member between a first position in which the light passes through the filter before reaching the positive meniscus lenses and a second position in which the light passes through the clear opening. An elongated tubular electromagnetic shield extends beyond the meniscus lenses.
