Оригинальный граненый обтекатель ИК-головки наведения британской ракеты воздух-воздух de Havilland Firestreak. Обтекатель составлен из пластинок стеклообразного сульфида мышьяка. Необычный материал был выбран из-за его высокого показателя преломления и широкого диапазона пропускания, что важно для чувствительности инфракрасной головки
