This is the G390068322 optical flat window from Qioptiq Photonics, a leading provider of precision optics. The window is designed with a base shape of a flat circle, featuring a diameter of 12.7 mm and a thickness of 2 mm.
The window is made of N-BK7, a popular borosilicate glass known for its excellent optical properties, making it suitable for a wide range of applications. The N-BK7 Schott material ID ensures high-quality and consistency in the production of this optical component.
The window is designed to work optimally with a wavelength of 633 nm. It comes with anti-reflection coatings on both the front and back surfaces, specifically the qio bbar arb2visnbk7 coating. These coatings are designed to reduce surface reflections, thereby increasing transmission and improving overall system performance.
The window's shape is that of a thin lens, which is often used in optical systems to reduce weight and thickness while maintaining optical performance. This window is currently in stock and available for purchase on the Qioptiq Photonics website.
