摘要： An objective lens is configured of a first crown-glass lens and a second flint-glass lens, whereby it can exhibit substantially identical optical properties at a plurality of recording/reproducing light source wavelengths, particularly, in both 650 nm and 405 nm wavelength bands. Also, by maximizing the difference in glass transition point between the first and second lenses, one of the first and second lenses having a higher glass transition point is molded first, to allow that first molded lens to serve as a mold tool for molding the other lens. This dispenses with the steps of aligning and adhesive bonding the two lenses, whereby this objective lens can be used at a plurality of wavelengths as a single objective lens, and thus an information recording/reproducing apparatus can be of a simple configuration.

摘要： To produce a wavelength plate that is superior in durability and stability and has a high moisture resistant property. A dielectric material is obliquely vapor deposited on a substrate so as to form a birefringent layer that has columnar portions in each of which fine particles of the dielectric material are stacked in a columnar shape, and interstices that are respectively formed between the columnar portions, and the birefringent layer is subjected to an annealing treatment at a temperature within the range of 100° C. or more to 300° C. or less. Then, a protective film with low moisture permeability is formed on the annealed birefringent layer by forming an inorganic compound on the birefringent layer at high density.
