Our flat or concave superpolished research grade mirror substrates offer surfaces better than 1 Angstrom surface roughness. When combined with our high reflectivity / low loss IBS coatings, these mirrors lead the industry in efficiency and performance. These mirrors are offered in standard fused silica, zerodur, and silicon substrate material and in varying standard sizes. GO can provide similar performance using other materials and we would be pleased to quote different sizes and shapes per your requirements.
