36-206 15 mm Dia. AR Coated Sapphire Protective Flat Window

The 36-206 is a high-quality protective flat window offered by Edmund Optics. This window, designed for general-purpose use, boasts a diameter of 15 mm and a thickness of 2 mm, making it a robust and reliable option for various applications.

The window is made from sapphire, a material with the chemical formula Al2O3, which is known for its exceptional hardness, making it resistant to scratches and abrasions. Sapphire also offers excellent optical clarity, ensuring minimal distortion and loss of light.

The 36-206 window features anti-reflective (AR) coatings on both the front and back surfaces. These coatings are made from magnesium fluoride (MgF2) and are designed to reduce reflection and increase transmission across the visible spectrum, specifically at 587.6 nm. The standard curve coating ensures optimal performance and durability.

The window's shape is defined as a thin lens, which is a lens with a thickness much less than its diameter. This shape contributes to the window's lightweight design and ease of integration into various systems.
