39-263 12.7 mm Dia. AR Coated Sapphire Protective Flat Window; t=3.2 mm NIR II 750-1550nm

The 39-263 is a 12.7 mm diameter flat window designed for use in the near-infrared (NIR) spectrum, specifically within the range of 750-1550nm. This window is sourced from the reputable optical vendor, Edmund Optics.

The window is made from high-quality sapphire, a material identified as al2o3 mal-1972-n-o in the material database. Sapphire is known for its exceptional durability and resistance to scratching, making it an ideal choice for protective applications. The window has a thickness of 3.2mm, providing a balance between strength and weight.

The 39-263 features anti-reflective (AR) coatings on both the front and back surfaces. These coatings are designed according to the standard NIR-II curve, which is specified as 'edm nir-ii std curve' in the item data. The AR coatings are crucial for minimizing light loss due to reflection, thereby enhancing the overall transmission efficiency of the window.

The window's geometry is defined by its circular base shape and thin lens shape. The circular base shape ensures uniformity in the direction of light propagation, while the thin lens shape minimizes optical aberrations.

The window's web links are provided for further information and purchasing. The link status is 'Valid - in stock', indicating that the window is readily available for immediate use.
