MgF2 Coated Windows
| Material: Diameter: Thickness: Surface Quality: |
Magnesium Fluoride ± 0.2mm ± 0.2mm <60-40 scratch/dig |
Note: Stectroscopic Standard Grade rectangular windows may be cut from the same sized diameter, so may have curved edges as a result. These types also come in drilled (with 30mm spacing)/undrilled versions for use alone or as a pair.
MgF2 Coated Windows – High-Performance Optical Solutions
MgF2 (Magnesium Fluoride) Coated Windows are widely used in optical applications due to their excellent transmission range from the UV to the IR spectrum (120nm–7µm). The MgF2 coating enhances performance by reducing surface reflection and improving transmission efficiency, making these windows ideal for lasers, imaging systems, and scientific instruments.
Key Features of MgF2 Coated Windows:
✔ Broad Spectral Transmission – Effective from deep UV to mid-IR.
✔ Anti-Reflective Coating – Reduces reflection and enhances optical clarity.
✔ High Durability – Chemically stable and resistant to environmental factors.
✔ Versatile Applications – Suitable for UV lasers, spectroscopy, aerospace, and medical optics.
