Sight Glasses

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. Original Leybold sight glasses are renowned for their exceptional quality and precision, offering a diverse range of optical materials and coatings with low absorption and high transmission properties, depending on your needs. Designed to withstand high temperatures and chemical exposure, these sight glasses make the perfect addition to your vacuum system.
