Determination of the Optical Characteristics of Complexly Structured, Locally Modified Regions in Quartzoid Glass

The focal length and numerical aperture of a complexly structured modified region in a plate of porous glass are determined. It is shown that when a plate of porous glass with a modified region is baked the complex structure of the modified region remains. The focal length and numerical aperture of the complexly structure modified region in the quartzoid glass plate are determined. It is found that baking a porous glass plate with a modified region in a furnace considerably reduces the focal length and increases the numerical aperture to 0.9.
