STEEP-EDGE
LONGPASS FILTERS
.
Andover's steep-edge longpass filters feature magnetron sputtered hard oxide coatings, yielding deep rejection to greater than OD 4, and a sharp transition slope of ¡Â 1% to very high transmission. The coatings are deposited on precision-polished Fused Silica substrates, and do not employ any absorbing filter glass, making them suitable for high temperature applications.
