How to Choose

  • Define wavelength and angle: select line-specific or broadband dielectric HR if peak reflectivity is critical.
  • Pick substrate by energy/UV: use fused silica for UV and high fluence; H-K9L for VIS–NIR general use; float glass for cost-sensitive paths.
  • Match geometry to task: flat for steering, spherical for focusing, cylindrical for line focus, ellipse/prism for compact folds.
