A system comprising a cylindrical housing containing a sorbent cartridge selective of one or more gases in a gaseous mixture. End caps on opposite ends of the housing seal to the ends of the cartridge and direct the flow of gas mixture through a portion of the cartridge. The first end cap has entrance and exit ports for the gas mixture and for a purging gas for cartridge regeneration. The second end cap includes a compartment to receive and return the gas mixture to the first cap exit port. The purging gas follows a similar pathway via the remaining portion of the cartridge. The cartridge is rotatable within the housing; thus, the exhausted portion of the medium may be rotated into position for regeneration while a regenerated portion of the medium is rotated into position for re-use, thus providing continuous adsorption from the gas mixture.

An antireflection coating includes one or more inorganic antireflection layers (typically metal oxide or silica layers) and a polymer layer cured in situ, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 to 700 nm and a thickness of from about 20 to about 200 nm. The polymer layer provides good scratch and fingerprint protection, and also enables the thicknesses of the inorganic antireflection layers to be reduced, thereby reducing the cost of the coating.
