H-K9L Glass Wafers

H-K9L is an excellent less expensive alternative BK7 glass.

H-K9L is a great subsitute for fused silica when extremely hard glass is not required. H-K9L benefits includes:

  • low refractive index
  • low dispersion
  • excellent transmittance through-out the visible and near infrared spectra
