ИССЛЕДОВАНИЯ ПОВЕРХНОСТИ ОПТИЧЕСКИХ СТЕКОЛ МЕТОДОМ ИНТЕРФЕРОМЕТРИИ БЕЛОГО СВЕТА

Topographic surface studies of optical glasses after they come in contact with a moist atmosphere are carried out by white-light interference microscopy. It is shown that the roughness changes are minimal in silicate glasses and maximal in borosilicate glasses, while borate glasses occupy an intermediate position. The increase of the roughness in silicate glasses is caused by the growth of peaks on the surface and in borosilicate and borate glasses by the growth of both peaks and valleys.
