As SST continues to expand our product catalog, we are excited to announce the addition of our new line of extended-range viewports. Specialized for operation across a broad spectral range, our new viewport options include Magnesium Fluoride, Calcium Fluoride, and Zinc Selenide windows.

Calcium Fluoride (CaF2) Viewports:

• Benefits: Wide transmission range from UV to infrared, good thermal conductivity, and low refractive index
• Common Applications: Infrared spectroscopy, optical systems, and laser applications

Magnesium Fluoride (MgF2) Viewports:

• Benefits: Excellent transmission in the ultraviolet (UV) and near-infrared (NIR) spectral regions, good thermal stability, and low refractive index
• Common Applications: UV and NIR spectroscopy, optical metrology, laser systems, and environmental monitoring

Zinc Selenide (ZnSe) Viewports:

• Benefits: Excellent transmission in the mid-infrared (MIR) spectral region, high refractive index, and good mechanical properties
• Common Applications: Infrared imaging, gas sensing, laser systems, and thermal imaging

Choosing your hermetic extended-range viewport depends on specific requirements.

• Operating temperature range: Consider the minimum and maximum temperatures the viewport will encounter.
• Pressure conditions: Evaluate the pressure environment, whether it's vacuum, high-pressure, or atmospheric.
• Optical requirements: Determine the required spectral range, transmission, and optical quality.
• Chemical compatibility: Consider the chemicals and substances the viewport will be exposed to.
• Mechanical properties: Evaluate the required strength and durability of the viewport.

By carefully considering these factors, SST engineers work with our customers to select the most suitable viewport for your hermetic environment. Our sapphire viewports, Kodial Glass viewports, and now the above extended-range viewports provide customers with the variety of hermetic viewport options backed by SST’s customer-focused staff and industry-leading quality.

SST’s hermetic feedthroughs, connectors, and vacuum accessories can be found around the world in applications including semiconductor manufacturing, medical devices, and imaging equipment. And engineers of all types use SST products for groundbreaking projects such as energy storage, physics research, and even space exploration.
