G390043322 31.5 mm Dia. N-BK7 Optical Flat Window; t=3mm 450-700nm

The G390043322 is a high-quality optical flat window, boasting a diameter of 31.5 mm and a thickness of 3 mm. This window is crafted from N-BK7, a popular borosilicate glass known for its excellent optical properties, making it an ideal choice for various applications. The window is sourced from Qioptiq Photonics, a trusted name in the field of precision optics.

The window features anti-reflective coatings on both the front and back surfaces, specifically the Qio Bbar Arb2visnbk7 coating. This coating is designed to minimize reflection and optimize transmission within the visible spectrum, particularly at the wavelength of 633 nm. This makes the window particularly suitable for applications that require high transmission and low reflection, such as imaging systems, beam delivery systems, and optical testing setups.

The window's geometry is defined as a thin lens, suggesting that it can also be used in focusing applications, although its primary function is to provide a transparent barrier without introducing significant optical aberrations. The window is currently in stock and available for immediate purchase through the Qioptiq Photonics website.
