摘要： The present invention relates to optical power-limiting device, and more particularly, to an optical power-limiting passive device and to a method for limiting optical power transmission in lenses and windows, using absorption changes in a novel photochromic composition, having response to infrared light in addition to the conventional response to ultra violet light. This additional response is featuring the use of the novel photochromic composition in places where ultra violet and short wave visible light is absent, or obscured, e.g. using photochromic glasses behind the front window of a car.
