This is a high-quality optical window from Qioptiq Photonics, designed for precision applications. The window, identified as G390139329, features a flat design with a diameter of 22.4 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical systems.
The window is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material, also known as Schott glass, is known for its low auto-fluorescence, high damage threshold, and excellent transmission in the visible and near-infrared regions.
The G390139329 window is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is specifically designed for use with YAG lasers at 1064 nm, reducing surface reflections and improving transmission.
The window's thin lens shape allows it to be used in various optical arrangements, while its flat design ensures minimal distortion. The window is currently in stock and available for purchase on the Qioptiq Photonics website.
