| This behavior is also common in two-material waveplates such as achromatic waveplates constructed from quartz and magnesium fluoride plates. |
| In 1935, Zeiss found a coating of magnesium fluoride on glass lenses dramatically improved image quality. |
| Each tube received an aliquot of 100 ml of sodium fluoride solution and was sealed and shaken in a bath maintained at 298 K for 3 hours. |
| Professional topical fluoride application is an adjunct to oral fluoride supplementation used for the prevention of dental caries. |
| The report also called for more research on fluoride and the implications for child health. |
| Quartz-sapphire and quartz-lanthanum fluoride achromats provide better performance. |
