G390139525 22.4 mm Dia. N-BK7 Optical Flat Window; t=3.5mm 725-1050nm

This product is a high-quality optical flat window, offered by the renowned vendor Qioptiq Photonics. It is designed with a base shape of a circle, featuring a diameter of 22.4 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical applications.

The window is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. This material is known for its low coefficient of thermal expansion, making it resistant to thermal shock. It also has a high Abbe number, which reduces chromatic aberration, making it an ideal choice for applications that require high image quality.

The window is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the window in the spectral range of 725-1050 nm. The coating also provides excellent environmental stability, ensuring the window maintains its performance even in harsh conditions.

The window is shaped as a thin lens, which is beneficial for applications that require minimal optical path length distortion. This feature, combined with its high-quality material and coating, makes this window an excellent choice for various optical systems.
