G390020525 80 mm Dia. N-BK7 Optical Flat Window; t=10mm 725-1050nm

The G390020525 is a high-quality optical flat window, sourced from the renowned vendor Qioptiq Photonics. This window, with a base shape of a circle, has a diameter of 80 mm and a thickness of 10 mm, making it suitable for a wide range of optical applications.

The window is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material, also known as Schott glass, is characterized by a low coefficient of thermal expansion and high transparency in the visible and near-infrared regions. The N-BK7 Schott glass used in this window ensures high-quality optical performance and durability.

The G390020525 is designed for use with a central wavelength of 633 nm, making it suitable for applications that require high transmission in this region. The window features broadband anti-reflection coatings on both the front and back surfaces. These coatings, identified as Qio Bbar Arb2nirnbk7, are designed to minimize reflection and increase transmission, thereby enhancing the overall performance of the optical system.

The window's shape is defined as a thin lens, indicating its suitability for use in systems where a flat window is required but where some degree of focusing or collimation may also be needed. This versatile window is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
