UV-fused silica convex lenses Synthetic fused silica offers high transmission imaging in ultraviolet applications and can be used (down to 170nm) although used mostly in UV applications synthetic fused silica also performs well in the visible and NIR. UV synthetic fused silica also has very low fluorescence, excellent thermal properties and high resistance to radiation and to chemical attack. UV synthetic fused silica Lenses are available uncoated or with multiplayer AR coating for 248-400nm.
