Schoonover is pleased to offer vacuum viewports in high vacuum and ultra-high vacuum for a wide range of vacuum applications. A number of window options are available to cover light wave frequencies required by many photonic applications. Options such as anti-reflective coatings are available upon request.
The window sizing of vacuum viewports, with provided viewable areas, goes up to 3 inches. Flanges can be weldable, ConFlat or Quick Flange (NW, KF & QF). Custom capabilities include pressure & temperature options. Vacuum viewports with different optical finishes such as surface polish, flatness, parrallelism, clear aperature, wedge angle, focal length and thickness are also available.
Kodial glass viewports are manufactured from 304 stainless steel and alkali borosilicate 7056. Kodial glass allows for the operator to view a process, make measurements of emissions, and initiate chemical action from a specific wavelength. Usable to temperatures of 200°C.
UV Fused Silica
Fused Silica Viewports are available with diameters up to 8 inches and include zero length designs for low profile applications. These are all bakeable to 200˚C. Several standard grades of Fused Silica windows are offered and have excellent transmission from 193nm to 2 microns.
DUV Fused Silica
Deep (DUV) Fused Silica Viewports are available with diameters up to 8 inches and include zero length designs for low profile applications. These are all bakeable to 200˚C. Several standard grades of Fused Silica windows are offered and have excellent transmission from 193nm to 2 microns.
EUV Fused Silica
Extended Range UHV
Laser Optics Fused Silica Viewports pair a specific type of Fused Silica with a precise AR V-Coating specific to your laser wavelength. These viewports are bakeable to 200˚C. We have four standard wavelengths: 193nm, 248nm, 780nm, and 1064nm. If you need a wavelength, please contact Apex Vacuum and we will assist you to get the best performing viewport for your application.
