NEW INVENTION
GLASS WITHOUT SILICA. Discovery of a new kind of glass which is giving American military aviation improved aerial photographs was announced recently by the Eastman Kodak Company. The glass is made without silica,
a fact as strange as steel made without iron. The result is glass whiqh bends light more than has hitherto been possible. Applied to a camera lens, this means that, without reducing speed, the new “ eye ” will photograph a wider area and at the same time give a sharper picture over the entire area. The new glass was perfected a year ago, and kept secret, but the news came out recently in the annual stockholders’ report. Aerial lenses for the Government have been manufactured for the last year.
