Sputtered UV Filters
UV filters can be designed with metal/dielectric/metal stacks. These designs can be fabricated for applications across the VUV and UV. An example of a 220nm bandpass is shown below. Spectral width is adjustable via the number of cavities in a design. These filters are quite robust in humid environments.
Omega fabricates these UV designs by sputtering thin metals and dielectrics in the chamber shown below.
