Vacuum Viewports

Vacuum Viewports: Clear Performance Under Pressure

In high-performance systems where vacuum integrity and optical clarity are paramount, vacuum viewports—also known as vacuum windows, hermetic windows, and hermetically sealed viewports—are indispensable. These components serve as critical interfaces between atmospheric and vacuum environments while allowing precise optical transmission for lasers, infrared, and imaging technologies. At the forefront of innovation, Complete Hermetics delivers customized hermetic products designed for challenging operational demands in space, defense, medical, and industrial sectors.

Custom-Engineered Hermetic Viewports

Unlike standard optical windows, hermetic viewports must maintain vacuum integrity under extreme environmental conditions. Complete Hermetics specializes in custom hermetic seals and feedthroughs, offering advanced window assemblies that conform to MIL-PRF-13830 and MIL-O-13830 standards. Whether for deep-space missions or high-power laser applications, these glass to metal seals and ceramic to metal seals  deliver unmatched performance and reliability.

Each unit is built to meet client-specific requirements—size, shape, optical transmission, thermal endurance—across a broad range of material configurations. Typical window materials include Sapphire, Fused Silica, Glass, Magnesium Fluoride, and Zinc Selenide. For flange materials, options such as Stainless Steel (CF/NW), Kovar, Titanium, and Aluminum ensure mechanical compatibility and chemical resistance.

Uncompromising Performance Standards

Every viewport from Complete Hermetics undergoes rigorous testing to ensure zero compromise on sealing integrity. These custom hermetic seals maintain leak rates of less than 1×10⁻⁹ Atm·cc/sec He and withstand bake-out temperatures up to 450°C, functioning reliably from -100°C in cryogenic setups to extreme high-heat applications. Optical elements are precisely aligned and polished to meet demanding military optical specifications.

Hermetic Headers: Protecting Electronics in the Harshest Environments

In the world of advanced electronics, hermetic headers play a pivotal role in safeguarding components from hostile conditions. These specialized components are essential to industries such as aerospace, medical, and defense, where protection from moisture, gases, temperature extremes, and pressure variations is non-negotiable. As a trusted hermetic seals manufacturer, Complete Hermetics designs and fabricates high-performance headers and terminals that preserve the integrity of sensitive electronic systems.

Multiple Pin Headers for Superior Connectivity

Multi pin headers are crucial in connecting various electronic systems while maintaining an airtight seal. Built for durability and precision, these components are engineered to thrive in extreme environments. From aircraft control systems to implantable medical devices, multi pin headers ensure uninterrupted signal transmission without compromising the seal—delivering both performance and protection in equal measure.

TO Headers: Specialized Transistor Solutions

TO headers (transistor outline headers) are specially crafted for high-frequency and optoelectronic applications. Commonly used in TOSA (transmit optical subassembly) and ROSA (receive optical subassembly) configurations, these headers provide robust housing and hermetic protection for semiconductors and photonic components. At Complete Hermetics, every TO header is custom-designed to ensure the perfect fit and optimal function for your application.

Hermetic Connectors: Dependable Seals for Complex Systems

Another standout among hermetic products is the hermetic connector—essential for creating sealed electrical interfaces between different modules. These connectors are ideal for vacuum systems, undersea cables, or defense electronics where even the slightest leak could result in failure. Complete Hermetics offers both standard and custom configurations to meet your exact requirements.

Vacuum Viewports

Best Custom Vacuum Viewports for Precision Optical Applications

In industries where performance under extreme vacuum and temperature conditions is non-negotiable, vacuum windows—also known as hermetic windows, high vacuum viewports, or hermetically sealed viewports—are essential components. These specialized hermetic products serve as transparent barriers that maintain airtight seals while allowing optical, laser, or infrared transmission in vacuum systems.

Engineered for High Vacuum Precision

Custom vacuum viewports play a critical role in maintaining system integrity in high-stakes applications such as defense optics, space instrumentation, medical endoscopy, and laser designation. These components must meet demanding specifications for both optical clarity and hermetic sealing. Complete Hermetics stands at the forefront of this technology, offering precision-engineered high vacuum viewports that are manufactured to meet or exceed MIL-PRF-13830 standards.

Advanced Materials and Construction

To deliver reliability across harsh environments, Complete Hermetics provides hermetic windows in a variety of customizable materials:

  • Window Options: Sapphire, Fused Silica, Glass, Magnesium Fluoride, Zinc Selenide
  • Flange Materials: Stainless Steel (CF, NW), Kovar, Titanium, Aluminum

These materials are selected based on application-specific requirements such as thermal expansion, optical transmission range, and chemical resistance. All assemblies are leak-tested to a stringent <1×10⁻⁹ Atm·cc/sec HE rate and operate across an impressive thermal range from -100°C to 450°C.

Tailored to Your Specifications

From aerospace-grade sapphire windows to magnesium fluoride lenses for UV systems, each hermetically sealed viewport is custom-built in nearly any shape or size to integrate seamlessly with your platform. Whether you require circular, rectangular, or complex geometry, Complete Hermetics delivers solutions that ensure maximum performance and longevity.
