Abstract
PURPOSE: To prevent deposition of fine dust on lenses and prevent the degradation in quality by filling inert gas such as nitrogen or the like in a housing chamber which is shielded from the outside air by means of doors and storing the lenses in the moisture-free inert gas.
CONSTITUTION: Suitable cases storing therein lenses are placed on the storage racks 4 in a housing chamber 1 and doors 2 are closed to assume a hermetic state. Next, the specfied water-free gas is supplied through a gas feed pipe 9 into a supply chamber 5 from a high pressure vessel 10. The gas gradually enters a moisture-free atmosphere chamber 6 through the vent holes 3 provided in a diffusion plate 4. A gate valve 8 is closd when a detector 12 becomes non-operating upon filling of the moisture-free gas and complete exhausting of the atmospheric air component. By storing lenses in such a storage house, the progression of the tarnish phenomenon caused by moisture may be decelerated and the degradation in quality may be prevented.
