The Features and Applications of Silicon Windows and Magnesium Fluoride Window

Optical windows made of crystalline magnesium fluoride are known as MgF2 windows. It is a robust, strong optical substance suitable for use in many challenging circumstances.It is extremely resilient to mechanical, thermal, and chemical etching and hence it is ideal for harsh environments.From the deep UV to the mid-infrared, MgF2 shows stunning broadband transmission from 120 nm to 8 m. These windows are a popular choice for UV polarizer and excimer laser applications and are frequently used as UV viewpoints. It is often used for optical elements in the infrared that require extreme durability and roughness.

The melting point of magnesium oxide is 1255 degrees Celsius. It has a tetragonal crystal structure and a density of 3.177 g/cm3. As it is softer than fused silica, one must be careful when handling MgF2. However, at HK576, it is the hardest of the optical fluorides. Magnesium Fluoride (MgF2) Windows from COE Optics have great broadband transmission varying from the deep ultraviolet to the mid-infrared. They are perfect for applications involving excimer lasers, the hydrogen Lyman-alpha line, UV radiation sources, and receivers due to their DUV transmission. With transmission greater than or equal to 60% T, magnesium fluoride (MgF2) windows can function at a 120 nm wavelength. In comparison to other companies' polycrystalline Magnesium Fluoride (MgF2) windows, COE Optics can provide single-crystal Magnesium Fluoride (MgF2) windows, which is much better. It is also occasionally used in biological and military imaging applications.

For reducing birefringence, COE Optics can provide with C-axis orientation accuracy of +/-1 degree. The Knoop Hardness of gF2 material is 415, and its index of refraction is 1.38.  MgF2 is a tough substance resistant to mechanical, thermal, and laser damage as well as chemical etching.

  • Excellent transmission between 120 and 8000 nm
  • Extremely durable
  • Chemical etch resistance; thermal and mechanical shock resistance
  • high laser damage threshold

COE Optics also specialise in manufacturing Silicon optics using optical grade silicon and have a wavelength range of 1.2 to 7 m. Usually, the transmitted signal is only slightly or not at all distorted. Due to its low density, Silicon has an advantage over other IR materials, making it perfect for optical systems where weight is an important consideration. With little to no distortion of the transmitted signal, silicon windows have good transmission in the 1.2 to 7.0 m range. These are also more durable and less fragile than germanium. COE Optics is a leading manufacturing supplier of optics and optical components customised to meet industry specific needs.
