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

Sapphire has superior optical transmission qualities for ball lens and half ball lens.
Ball lens is used to improve the signal coupling between optical fiber, transmitter and detector, improve the signal quality, and can also be used in endoscopy, bar code scanning, aspherical lens preprocessed materials, sensors, etc. The ball lens has a short focal length, which minimizes the distance needed to travel from the ball lens to the fiber. Ball lens commonly used in the optical fiber coupling, laser collimating device, Optical Measurement System, it has a shorter focal length and the characteristics of small size. Sunday produce ball lens, half ball lens, Super hemisphere ball lens, hollow ball lens.Sunday Optics can manufacture ball lens Minumum diameter 0.3mm.Sapphire has superior optical transmission qualities for ball lens and half ball lens.
