A rugged construction for an optically immersed infrared detector is provided along with a method of fabrication which produces an infrared detector which can withstand shock, vibration and high acceleration levels. A metallic base is formed with a cavity therein, along with electrical feed-through pins and a relief channel. Lead patterns are deposited on a thin sheet of insulating material and infrared detectors are mounted on the lead patterns and the sheet is assembled in the cavity of the base with the feed-through pins being connected to the lead pattern which makes electrical connections to the infrared detector through the appropriate feed-through pins. The cavity is filled with an immersion material and an infrared window, which may be in the form of a lens, is pressed into its seat in the base conveniently formed by a ledge surrounding the cavity. As the infrared window is positioned on its seat, any excess immersion material flows through the relief channel, and the assembly so formed is cured so that the immersion material solidifies.
