Magnesium Fluoride (MgF₂) is a widely used optical crystal known for its exceptional transparency from deep ultraviolet (DUV) to mid-infrared. It is commonly used in UV optics, spectroscopy, laser systems, aerospace optics, and semiconductor processing. What wavelength range does MgF₂ transmit? MgF₂ offers an extremely wide transmission range from approximately 120 nm to 7 µm, making it suitable for deep UV, VUV, visible, and infrared optical applications. Why is MgF₂ preferred for deep UV and VUV optics? MgF₂ has very low absorption in the deep UV and vacuum UV regions, excellent radiation resistance, and high environmental stability, making it ideal for excimer lasers, synchrotron optics, and UV spectroscopy. Is MgF₂ suitable for harsh or outdoor environments? Yes. MgF₂ is insoluble in water, resistant to moisture, and maintains stable optical performance over a wide temperature range. These properties make it suitable for aerospace, space optics, and long-term outdoor use. What forms and components are available? MgF₂ can be supplied as optical windows, substrates, prisms, polarizers, lenses, and fully custom optical components according to your design requirements. Can MgF₂ be used as an anti-reflection or optical coating substrate? Yes. Due to its low refractive index (~1.38), MgF₂ is widely used both as a coating material and as a substrate for UV and broadband optical coatings. Do you offer custom sizes, orientations, or polishing? Yes. We provide custom dimensions, thicknesses, crystallographic orientations, and optical-grade polishing to support research, prototyping, and OEM integration. Are MgF₂ crystals suitable for research and production use? Absolutely. Our MgF₂ crystals are supplied to universities, research laboratories, and industrial customers for both R&D and volume production applications. .product-faq { margin-top: 48px; } .product-faq h2 { font-size: 1.4rem; margin-bottom: 22px; } .product-faq details { border: 1px solid #e5e5e5; border-radius: 8px; margin-bottom: 12px; padding: 14px 18px; background: #fafafa; } .product-faq details[open] { background: #ffffff; } .product-faq summary { font-weight: 600; cursor: pointer; list-style: none; position: relative; padding-right: 28px; } .product-faq summary::after { content: "+"; position: absolute; right: 0; top: 0; font-size: 18px; } .product-faq details[open] summary::after { content: "–"; } .product-faq summary::-webkit-details-marker { display: none; } .product-faq .faq-content { margin-top: 12px; color: #555; line-height: 1.65; }
