For many applications in vacuum technology, it is necessary to observe the process area inside a vacuum chamber. Depending on the specific process, the requirements range from simple visual observation to precise optical measurements. Beyond pure observation, many vacuum technology applications require the targeted introduction of electromagnetic waves in the form of light or laser waves from the outside into the vacuum or from the inside out of the vacuum.
The wide range of applications not only results in a multitude of optical requirements. Depending on the specific conditions of use, the materials, flange systems, coatings etc. used must also be selected with regard to pressure, temperature and corrosion resistance, electrical and magnetic properties.
Standard view ports made of borosilicate allow easy observation or illumination of the inside of a vacuum chamber and thus ensure reliable monitoring of the function and performance of individual components or entire vacuum systems. For optical applications, the desired spectral range and thus the choice of optical material is crucial. novotek offers optical components in various materials such as fused silica, sapphire, zinc selenide, magnesium fluoride, calcium fluoride, germanium and quartz crystal.
