Diamond optical components
Natural IIa-type «nitrogen-free» diamond plates, windows and substrates. We offer double or single-side polished, plane-parallel discs made of specially selected IIa-type diamonds.
Substrates and plates with different dimensions and shapes, with fully documented parameters, including geometric, electrophysical and optical values, with or without specific crystallographic orientation, and also in metal-mounted modules or with metal deposited composition or single layer.
