Vacuum Viewports

The Quick Guide to Vacuum Viewports

When you have a vacuum system, the viewport is an optical component that provides energy transmission in and out of the system. These are hermetically sealed and ensure high-functioning. Here is what you should now.

Vacuum Viewports Explained

You may choose vacuum viewports when you can reach the target in the chamber in a straight line. In other cases, you may be able to use a small number of mirrors to reach the target directly. A vacuum viewport may have two components. The flange and window both need to be designed utilizing the best materials possible. The windows, for instance, may be made from the following materials:

  • Sapphire
  • Fused Silica
  • Glass

The flanges, on the other hand may use:

  • Aluminum
  • Titanium
  • Kovar

Neither of these lists are exclusive. Viewports may be manufactured with a number of different materials.

Applications for Vacuum Viewports

A vacuum viewport is hermetically sealed, to ensure that any mechanical devices perform at the highest and most efficient capacity. When you choose a vacuum viewport, you can use the components in infrared, laser and optical applications. If you’re worried about the viewports fitting the needs of your machine, they can satisfy a wide variety of requirements.

In terms of vacuum systems, a vacuum viewport is necessary for high-functioning. Your materials and needs, of course, will be dependent on the type of system that you own. It’s important to keep that in mind when making your choice.

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.
