Sight glasses, or also known as viewports, are crucial in vacuum technology for observing and illuminating processes within vacuum chambers.
They enable the transfer of electromagnetic waves, such as light or laser beams, into and out of the vacuum environment, essential for monitoring and controlling processes for example in semiconductor manufacturing, scientific research, and industrial applications.
