A must-see for government agencies, research institutions, and universities! We will introduce the viewing port (viewport) and current introduction terminals that our company handles!

This is the viewing port (viewport) from MPF Products in the United States. We offer materials such as zinc selenide (ZnSe), calcium fluoride (CaF2), magnesium fluoride (MgF2), fused quartz, sapphire, and viewing ports for lasers. Additionally, we can also manufacture custom products such as high-pressure viewing ports.

We are offering a "Comparison Table of 4 Types of Products" to help you select the appropriate hermetic products! We introduce features, temperature, pressure, and more for each product.

【Selection of Hermetic Components】 ＜Hermetic Feedthroughs & Connectors＞ ■Sealing Performance Ensured airtightness through high-strength, low-outgassing epoxy molding. ■Temperature: -50℃ to +150℃ ■Pressure: High vacuum to approximately 70 MPa ＜Ground Feedthroughs＞ ■Sealing Performance Airtightness is ensured by using various soft packing (sealants) and compression sealing. ■Temperature: -200℃ to +870℃ (varies depending on sealant material) ■Pressure: High vacuum to approximately 70 MPa ＜Ultra High Vacuum Hermetic Connectors＞ ■Sealing Performance Airtightness is ensured through the latest ceramic-glass bonding technology. ■Temperature: -200℃ to +250℃ ■Pressure: Ultra high vacuum to approximately 0.1 MPa ＜Current Feedthroughs & Viewing Ports＞ ■Sealing Performance Airtightness is ensured by metallizing ceramics and soldering them to terminals and housings. ■Temperature: -269℃ to +450℃ ■Pressure: Ultra high vacuum to approximately 0.1 MPa *For more details, please refer to the catalog or feel free to contact us.
