Abstract

A beacon with a preferably anodized aluminum body, cylindrical in shape, and threaded. The exact diameter and thread size of a water catcher cap is defined by the accompanying MWIR/LWIR beacon it threads onto. The accompanying component male thread allows the water catching cover to be threaded down completely for when the MWIR/LWIR beacon is powered on, thus creating an IR iris for the beacon emission, also while cooling the MWIR/LWIR beacon by being able to capture water within its open space cavity between the accompanying component and the water catching cover wall. Further in a wet environment, the open nature of the water catching cover permits rapid quenching by ambient water and refill of water catcher. Alternatively, when thread in the upmost position it protects the accompanying MWIR/LWIR beacon point of emission.

Claims1

Dependent claims

A Mid Wave Infrared or Long Wave Infrared (MWIR/LWIR) beacon comprising:

a housing, a cylindrical window projecting from the housing, and a window cap on the cylindrical window;
a water catching cover having cover threads mating with housing threads on the housing allowing the water catching cover to be threaded up and down to protect and expose the cylindrical window;
wherein an inner profile of the water catching cover comprises a shelf projecting radially outward from a diameter of the cover threads to an inner wall projecting upward to provide space between the inner wall of the water catching cover and an outer profile capable of retaining water to cool the beacon;
an attachment point comprising a ring integral with the water catching cover being recessed from an outer periphery of the water catching cover, an axis of a hole defined by the ring extending in a direction of a chord to outer periphery of the water catching cover;
and
grooved outer wall formed in an outer wall of the water catching cover such that a gloved hand can handle it and easily rotate it a.
