With the optional fiber jig cover, an optical fiber can be installed directly on the cover, allowing
in-situ optical experiments under controlled environments.
The fiber port is positioned at the center of the standard window cover. The optical fiber is attached
to the outer surface of the window, enabling light delivery or collection toward the sample inside the
chamber while maintaining vacuum integrity.
This configuration provides a convenient option for various optical access and fiber-based measurements
in combination with high-temperature or reactive-gas conditions.
