Vacuum Viewports

How Can High Vacuum Viewports Prevent Outgassing Risks?

Monitor your equipment or transmit energy into a sealed system using vacuum viewports by Complete Hermetics. Review the common uses of viewports and compare window materials today to find a product that fits your laser or infrared needs.

Typical Uses

The most basic use of a vacuum viewport is a window to view the interior of a sealed system. This application can assist you in monitoring the performance components in a vacuum. A more common application of hermetic viewports is to allow a wide spectrum of light to pass through in one or both directions.

Infrared and laser lights require a hermetic viewport to be transmitted through an otherwise sealed environment. A viewport plays a unique role in allowing a single type of light or wide spectrum light to send energy in and out of the hermetically sealed system. Here are a few industries where these components are commonly used:

  • Defense industry
  • Medical endoscopic fields
  • Space industry
  • Laser designation systems

Common Viewport Materials

Vacuum windows need to use specific materials to allow energy to pass through without compromising the structure of the chamber. These are the most common materials used by Complete Hermetics to create viewport windows:

  • Zinc selenide
  • Fused silica
  • Sapphire
  • Magnesium fluoride
  • Glass

Custom Hermetic Feedthroughs

What Are Electrical Feedthroughs For?

You might not think that there are many components that can be found in X-ray machines, transformers and furnaces. But electrical feedthroughs are commonly used in a wide variety of technologies to help make sure that electricity doesn’t escape and cause malfunctions. It is important to know what these feedthroughs are used for and to appreciate this important piece of technology that keeps so many different technologies running.

The Importance of Vacuums 

Creating a vacuum guarantees that the electricity being transported from one part of a machine to another does not get out. Vacuum feedthroughs effectively make sure that the electricity is distributed safely.

Using Seals

The key to creating a vacuum is the type of seal that is used. Hermetic feedthroughs use glass-to-metal seals and ceramic seals to create this vacuum. When building a new seal, it is extremely important that the materials used are able to withstand intensive use and not break down over time.

This is why many seals are made with glass and ceramics; these materials are designed to withstand extreme temperatures, as well as other wear and tear. Many of these seals are used in technology like furnaces that operate at extreme temperatures. Making sure the seals do not break down easily will make sure the machine runs smoothly.

Glass-to-Metal vs Ceramic-to-Metal Seals: Hermetic Seal Products

We at Complete Hermetics are proud to offer a diverse array of different seals and feedthroughs that make us stand out as a top-tier hermetic seal products. The type of seal that will be best for your needs depends on which industrial application you will be using it for. In this short article, you will learn about the differences between glass-to-metal and ceramic-to-metal seals.

Ceramic-to-Metal Seals

Ceramic can withstand higher temperatures than glass, so ceramic-to-metal seals are best used in environments with very high voltages and operating temperatures. One thing to keep in mind if you go with the ceramic-to-metal option is that due to the increased amount of labor it takes to make one of these, your wait time may be longer after placing your order.

Glass-to-Metal Seals

Glass is a good option to go for if the environment involves electrical currents, due to its insulating qualities. It is also ideal for a high-pressure environment, even though its temperature threshold is lower than that of ceramic.

Finding the Right Seal

If you have decided which type of seal is best suited to your needs, you may be wondering which size to get. At Complete Hermetics, we can custom-make the perfectly shaped seal for whatever application you have in mind.
