Kodial Glass Viewports

Kodial viewports are seen as the default standard for vacuum viewports when no special optical properties are needed except for transmission at visible wavelengths in order to see inside a vacuum chamber.

Key Features

Please see the image gallery for the transmission function (a plot of light transmission vs wavelength of the light)
