Atlas Pyrex® glass viewports are mounted
on aluminum hardware and designed for
welding directly into high vacuum aluminum
chamber walls. Our viewports are lightweight
and an economical alternative to comparable
stainless steel solutions. The glass substrate
is captured between two elastomer O-rings.
One gasket provides a vacuum seal, while
the other acts as a cushion to prevent direct
glass-to-metal contact. Other standard sizes
are available on request. Atlas also produces
customized polycarbonate port covers of
various sizes and shapes. Contact our sales
department for more information.
