Technology / product information

The "Synthetic Fused Silica Plano Concave Lens" is a high-quality optical lens made from synthetic fused silica. It features a flat surface on one side and a concave surface on the other, with a negative focal length. This lens is used for applications such as image reduction, light dispersion, and laser beam spreading, excelling particularly in high-temperature environments and UV wavelength applications.

Additionally, combining this lens with others allows for extended working distances and greater flexibility in optical system design.

The product comes standard as uncoated but is customizable with anti-reflection coatings or other specialized coatings upon request.
