DARPA, NASA and other institutions have been developing sensors that will image light from the UV all the way to terahertz frequencies. These will revolutionize much of the existing optics industry. However, there no refractive optics on the market that can cover such a large frequency range. Are you working on a technology that addresses this problem?
I am not working in the field but I think reflective and multi-stage diffractive optics (using for example refractive gratings or Fresnel masks) could make the work quite well.
Maybe you can have a look at my publications list.
We are developping metamaterials absorbing radiation from 200 nm to 4.5 µm with average absorption of 98% on this ultra broadband range.
Current work is going on for GHz using graphene.
Sincerely yours.
