A Quartz Glass with Sharp Cut-off at 2800 Å

JSGT 1939 V23 T372-T377

By the addition of a small quantity of stannic oxide to quartz a glass, similar in its physical properties to pure fused quartz, is obtained which cuts off sharply all radiation below about 2800 Å and has a very steep transmission curve in this region. Its characteristics, methods of fusion, properties and uses are discussed.
