Magnesium Fluoride Dome

MgF₂ domes are mainly used in the following areas:

• Military and Aerospace: Primarily serve as optical windows to protect sensors from environmental interference.

• Ultraviolet Optical Systems: Used as high-transmission windows in deep UV laser devices and UV spectrometers.

• Infrared Detection: Employed as protective covers in thermal imaging systems and infrared sensors, suitable for the mid-infrared band.

• Also used as optical windows or transmission components in harsh environments or scientific instruments.

Magnesium Fluoride Domes is also a infrared optical dome. It has feature the following:

• High transmission over a wide spectrum from 120nm to 7μm, suitable for multi-band systems.

• Low refractive index, with naturally low surface reflection, allowing high transmittance without additional coatings.

• MgF₂ domes can withstand temperatures above 300°C, are resistant to acids and alkalis, and offer strong mechanical stability.

Magnesium Fluoride domes are mainly manufactured through crystal growth, optical cold processing, and thermal press forming.

We offer diameters up to 500 mm large optical dome, with customizable shapes including notched domes, flanged hyper-hemispherical domes, and other hyper-hemispherical designs.

We can provide broadband anti-reflection coatings (BBAR), conductive ITO coatings, hydrophobic coatings, diamond-like carbon (DLC) coatings, and reflective coatings custom optical dome.
