These optical component are precision manufactured using UV-grade synthetic fused silica. In addition to superior transmission characteristics, synthetic fused silica exhibits higher thermal properties, exceptional purity, and excellent environmental durability for demanding applications.
Windows are designed for use in optical systems to separate two environments while passing a particular spectral range between them. Applications include laser set-ups, emitter/detector protection devices, and imaging systems involving ultraviolet wavelengths.
