MgF2 Optical Window
Magnesium Fluoride (MgF2) Windows
- Excellent Transmission from 120nm to 7μm
- Rugged and Durable
- Resistant to Chemical Etching
Magnesium Fluoride (MgF2) Optical Windows offer excellent transmission in the UV to infrared spectrum, making them ideal for a wide range of applications. These windows are highly durable, resistant to scratching, and perform well under extreme environmental conditions. MgF2 Optical Windows are commonly used in laser systems, spectroscopy, and optical instruments. Their low refractive index ensures minimal distortion, making them a popular choice in precision optics.
