Magnesium Fluoride (MgF2) Windows

Product Overview:

Magnesium Fluoride (MgF2) windows offer excellent broadband transmission from the deep-UV to the mid-infrared. This property makes it an excellent choice for UV radiation sources and detectors, including applications involving the Hydrogen Lyman-alpha line. Frequently, it finds use as a UV viewing window, serving as an ideal candidate for UV polarizers and excimer laser applications.

Features:

• Wide Transmission Range: MgF2 windows have an exceptionally broad transmission spectrum, from the deep ultraviolet (UV) to the infrared (IR) region, typically covering wavelengths from around 150 nm to 7 µm. This makes them ideal for applications requiring a wide range of wavelengths.

• Low Refractive Index: With a refractive index of approximately 1.38 at 589 nm, MgF2 windows exhibit minimal reflection losses, which is beneficial for applications where maximum light transmission is crucial.

• High Damage Threshold: MgF2 windows have a high laser-induced damage threshold, making them suitable for use in high-power laser systems where other materials might degrade or fail.

• Chemical Stability: MgF2 is chemically stable and resistant to many common environmental factors, including moisture and some chemicals, which ensures long-term reliability and durability in various operating conditions.

• Low Absorption: MgF2 windows have very low absorption across their transmission range, which means they can efficiently transmit light without significant energy loss.

• Mechanical Strength: Despite being a relatively soft material, MgF2 windows have adequate mechanical strength for most optical applications and can be polished to very high surface quality standards.
