G390069329 25.4 mm Dia. N-BK7 Optical Flat Window; t=5mm 1064nm

The G390069329 is a high-quality optical window, precision-engineered by Qioptiq Photonics. This window is designed for use in optical systems that require a flat, transparent element to maintain the path of light. With a diameter of 25.4 mm and a thickness of 5 mm, it offers a robust and compact solution for various applications.

The window is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared regions of the spectrum, making it a versatile choice for many optical systems. The window features a flat shape, ensuring that it does not distort the light passing through it.

The G390069329 is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, enhancing the performance of your optical system. The coating is optimized for a wavelength of 633 nm, but it also performs well at other wavelengths, making it a flexible choice for a wide range of applications.

In terms of geometry, this window is classified as a thin lens. This means that it has a thickness that is significantly smaller than its diameter, which helps to minimize optical aberrations. The window is available from Qioptiq Photonics, and according to the provided data, it is currently in stock.
