Material:

Flange : 304L SS

Sleeve : 4J29 Kovar

Window: Quartz(Fused Silica)

Flange : CF

Features:

• Built from the highest-quality materials to UHV standards
• Compatible with vacuum systems capable of reaching UHV levels
• Viewports may be sealed with fully annealed copper gaskets to reduce induced strain
• If the process deposits material, we strongly recommend a viewport shutter because deposits can damage and impair the optical properties of the lens.

Applications:

As quartz and sapphire have penetration of UV and infrared rays. They are generally used in vacuum systems, not only to observe the internal conditions of the vacuum cavity.

At the same time, quartz and sapphire can resist high temperature, they are also using in measuring temperature, photography, or camera functions.
