Sunday Optics offer 600mm size window with full CA test by 24 inches Zygo Interferometer The Standard Window Glass is N-BK7 or Fused Silica, but when manufacture,Fused Silica is more easy to keep its flatness stability. UV Fused Silica is better for UV wavelength, high power laser, the UV tranmission can be 185nm. BK7 Glass is aways used for visible light and near infrared, it is more economy and used for low laser as a protect window.Sunday Optics advantange is: within 600mm windows, we can offer full CA test reports, 1/10 lambda at 600mm is achieved. Specifications: Material BK7 K9 Fused Silica, Corning Fused Silica Size 1mm to 800mm Tolerance +/-0.01mm Parallisam
