UV fused silica features excellent UV Transmission unlike other common optical glasses like N-BK7; very low coefficient of thermal expansion. It’s highly stable and its optical properties won’t change significantly with temperature fluctuations. The extreme purity of UVFS eliminates microscopic defects that could be damaged by high-power lasers. UVFS doesn’t fluoresce under UV light, preventing unwanted light emissions that could interfere with sensitive measurements.

Both surfaces of bi-convex lenses are spherical and have the same radius of curvature, minimizing aberrations in situations where the object and image distances are equal or nearly equal. As a guideline, bi-convex lenses are the best choice for minimizing aberrations if the conjugate ratio (object distance : image distance) is between 5:1 and 1:5. Outside this range, plano-convex lenses are usually preferred.
