The OFSCN® Fiber Optic Vacuum Sealed Flange is a specialized component designed for transmitting optical signals into or out of vacuum chambers while maintaining high-level hermetic integrity. These flanges are critical for applications involving Fiber Bragg Grating (FBG) sensors or distributed fiber sensing within vacuum or ultra-high vacuum (UHV) environments.

Technical Overview

According to our technical specifications, these flanges are available in two primary series:

  1. KF Series: Commonly used for quick-release vacuum systems.
  2. CF Series: Designed for ultra-high vacuum environments requiring metal-to-metal seals.

Key Parameters:

  • Vacuum Level: Excellent performance with ratings better than 1 \times 10^{-5}\text{ Pa} and up to 1 \times 10^{-7}\text{ Pa}.
  • Temperature Range: Standard versions operate at room temperature, but custom versions capable of withstanding up to 250°C are available for bake-out or high-temperature processes.
  • Configuration: Supports both male and female connectors, and can be customized as single-channel or multi-channel feedthroughs.

Application and Mapping

These flanges are typically used to connect external OFSCN® Fiber Bragg Grating Interrogators to internal sensors, such as the OFSCN® 300°C Fiber Bragg Grating Temperature Sensor or various distributed sensors, without compromising the vacuum seal.
