39-233 25.4 mm Dia. AR Coated Sapphire Protective Flat Window; t=2.3 mm MgF2 400-700nm

This 39-233 optical window, sourced from Edmund Optics, is a 25.4 mm diameter sapphire window with a thickness of 2.3 mm. Sapphire, with the material ID al2o3 mal-1972-n-o, is a highly durable and scratch-resistant material, making it an ideal choice for protective windows.

The window features anti-reflective (AR) coatings on both the front and back surfaces. These coatings are made of magnesium fluoride (MgF2) and are designed to provide high transmission in the 400-700 nm spectral range. The AR coating on the front surface is standard curve edm mgf2, while the back surface is also coated with the same edm mgf2 std curve.

The window is shaped as a thin lens, which is a type of lens where the thickness is much less than the radius of curvature. This shape is often used in optical systems where the lens needs to be as thin as possible to minimize optical aberrations.

The window is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/p/254mm-diameter-mgfsub2sub-ar-coated-sapphire-window/40127/.
