High Temperature Vacuum Viewport (2018)

Low Cost KF50 Sapphire Viewport 270°C

Thoughtventions Unlimited, LLC, a world leader in custom high pressure, high temperature, high vacuum and low temperature viewports, is pleased to announce its latest product.

Until now sapphire viewports have been very expensive. As a result of long experience in custom viewports, Thoughtventions has developed proprietary bonding and sealing techniques that lower the cost and simplify the use of sapphire viewports.

As an initial standard commercial offering, a KF-50 sapphire vacuum viewport offers an affordable, quick-fitting sapphire aperture of high optical quality at a slight premium over available borosilicate viewports.

Other sizes will be available in the future.
