Description
General Introduction: The Raytek Magnesium Fluoride optical window is transparent in a wide spectral range of 120nm to 8uM. Magnesium fluoride has durability, heat resistance and mechanical shock resistance, and has high laser damage threshold..
Since MgF 2 has the lowest refractive index in all optical glasses, the antireflective coating does not need to have low surface reflectance. Therefore, the window is not limited to the spectral band of broadband antireflective film, and can be used at any wavelength from deep ultraviolet to infrared (120nm - 8μm). This is ideal for applications requiring simultaneous transparency at multiple wavelengths, such as spectral or fluorescent imaging of samples in vacuum. Due to the transparency of deep UV, the window can also be used in excimer laser applications
