Our fused silica bi-convex lenses are manufactured from high quality optical grade synthetic fused silica.Fused silica transmits in the UV region and to a certain extent in the near IR. It has an extremely low coefficient of expansion and can be safely used at high temperatures.

Most of these lenses are manufactured at our factory in Newquay.

If you can not find the lens you require in our catalogue we will be pleased to quote for a lens to your own specification.
