Viewports
Vacuum components from VACOM
Viewports are suitable for various vacuum optics applications: from general process observation and illumination to the precise and efficient transport of optical signals.
Subgroups
Standard KF/ISO
Thanks to their large clear view diameter, standard viewports with KF/ISO flange connections are ideal for observing and illuminating processes in rough, medium and high vacuum.
Standard CF
Standard viewports with CF flanges make it possible to illuminate and observe processes in UHV through borosilicate windows or, using fused silica, to also transmit light in the UV range.
Fused silica viewports for optical applications
UHV viewports with windows of high optical quality and anti-reflection coatings allow precise and efficient transport of light between vacuum and atmosphere.
Viewports for UV/IR applications
Viewports for the extended spectral range allow light to be transmitted deeper into the ultraviolet (UV) and infrared (IR) spectrum using optical materials such as CaF2, ZnSe, sapphire or crystal quartz.
Non-magnetic viewports
Non-magnetic viewports are characterised by their low magnetic susceptibility, making them suitable for applications that are sensitive to magnetic interference fields. AR coatings are available on request.
AluVaC® Optics
Our AluVaC® Optics viewports, with all-aluminium CF flanges and UHV-compatible bonding technology between window and flange, are ideal for minimising magnetic interference fields and weight. AR coatings are available on request.
Viewports with ITO coating
A vacuum-side coating of electrically conductive ITO (indium tin oxide) dissipates charge carriers that can build up on window surfaces depending on the application.
Radiation shielding caps
Radiation shielding caps can be mounted on the atmosphere side of CF viewports to protect against high-energy radiation when observing processes in vacuum.
CF viewport shutters
Viewport shutters protect the windows of viewports from contamination or damage caused by processes inside a vacuum chamber.
Optical viewports from novotek
Magnesium fluoride, germanium, EUV fused silica, windows with KF and ISO-K flange
Which component fits?
Nominal diameter, flange type, pressure range and material determine the choice. We advise you, put together components from the entire VACOM range and also source special versions.
