Vacuum Viewports / Windows

---

Concept Vacuum have developed a range of demountable viewports, enabling our customers to change the O-ring sealed optics without having to replace the complete vacuum window. This is particularly useful if optic damage is expected, for example in high power laser applications. Constructed from stainless steel 304L (1.4306) with an aluminium alloy retainer, our viewports can be installed on standard vacuum ports (KF, ConFlat®, ISO) - no special adaptors or fittings are required. 

Optic materials available are borosilicate glass, UV grade fused silica, sapphire, zinc selenide (ZnSe), magnesium fluoride (MgF2), barium fluoride (BaF2) and calcium fluoride (CaF2). If you would like to use another material, we may still be able to help you, so get in touch for a speedy quotation. 

These demountable viewports are suitable for mounting on high vacuum chambers . They are supplied cleaned to UHV standards and helium leak tested.

Instructions are supplied to inform you how to maintain your viewports and change the optics. 

We can offer standard glass sealed, bonded and brazed viewports (KF, ISO and CF) via our partner ultrahighvacuum.com - get in touch today for a price or friendly advice on your application.

Concept Vacuum supply viewports for high vacuum and ultra-high vacuum systems. We can can also supply them with thin film coatings - layers of material are deposited on a substrate to alter the optical properties. These coatings are used in a wide variety of applications, including:

• Anti-reflection coatings
• Beam splitters
• Filters
• Mirrors
• Polarizers
• Waveguides

Types of Optical Thin Film Coatings

There are two main types of optical thin film coatings: metal coatings and dielectric coatings.

• Metal coatings are made up of a single layer of metal, such as gold, silver, or aluminium. These coatings are highly reflective and are often used in mirrors.
• Dielectric coatings are made up of multiple layers of dielectric materials, such as magnesium fluoride. These coatings are typically designed to have anti-reflection optical properties.

Advantages of Optical Thin Film Coatings

Optical thin film coatings offer a number of advantages, including:

• High performance: Our optical thin film coatings are designed to have very high performance,.
• Durability: Our optical thin film coatings are often very durable and can withstand harsh environments.
• Cost-effectiveness: Our optical thin film coatings can be cost-effective, especially when used in large quantities.
