Viewport Magnesium Fluoride Zero Length Conflat Flange

This Magnesium Fluoride (MgF₂) Viewport is designed for high-vacuum and ultra-high-vacuum (UHV) applications, featuring a zero-length design mounted on a 2.75-inch Conflat (CF) flange. Known for its broad transmission range from vacuum UV to infrared, Magnesium Fluoride is ideal for spectroscopy, UV optics, and laser applications.

Key Features:

• Material: Magnesium Fluoride (MgF₂) – excellent UV and IR transmission

• Flange Size: 2.75″ Conflat (CF)

• Design: Zero length – minimal axial protrusion for space-sensitive setups

• Vacuum Compatibility: Suitable for UHV environments

• Applications: Spectroscopy, UV laser systems, vacuum chambers, scientific instrumentation

Specifications:

• Transmission range: ~120 nm to 7 µm (depending on thickness and coating)

• Durable and thermally stable

• Leak-tight seal with standard CF knife-edge and copper gasket

• Compatible with standard 2.75″ CF hardware

This MgF₂ viewport provides high transmission and low birefringence, making it ideal for research, optics, and laser integration in vacuum systems.
