G390137525 20 x 30 mm N-BK7 Optical Flat Window; t=2.5mm 725-1050nm

This is a 20 x 30 mm N-BK7 Optical Flat Window, a high-quality optical component sourced from Qioptiq Photonics. The window, which has a thickness of 2.5mm, is designed for use within the wavelength range of 725-1050nm, making it suitable for a variety of optical applications.

The window is made from N-BK7, a popular type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The window's rectangular shape, with dimensions of 20mm by 30mm, provides a large aperture for light transmission.

The window features a thin lens shape, which is designed to minimize optical aberrations and distortions. This makes it ideal for use in applications where high optical precision is required, such as in imaging systems, beam shaping, or laser applications.

Both the front and back surfaces of the window are coated with a Qio Bbar Arb2nirnbk7 coating. This anti-reflection coating is designed to reduce surface reflections and increase transmission, enhancing the window's performance in high-transmission applications.

The window is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
