G390139000 22.4 mm Dia. N-BK7 Optical Flat Window; t=3.5mm Uncoated

The G390139000 is a high-quality optical flat window, sourced from the reputable vendor Qioptiq Photonics. This window, with a base shape of Circular, is designed for use in a variety of optical systems, offering excellent transparency and durability.

The window has a diameter of 22.4 mm, providing a substantial surface area for light transmission. The thickness of the window is 3.5 mm, striking a balance between robustness and minimal interference with the light path. The material of the window is N-BK7 Schott, a widely used borosilicate glass known for its excellent optical properties, including high transparency and low dispersion.

This particular window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain properties such as reflectivity or transmission, an uncoated window offers simplicity and versatility, making it suitable for a wide range of applications.

The window is designed for use at a wavelength of 633 nm, although its properties may be suitable for use across a broader spectrum. For more detailed information on the window's performance at different wavelengths, please refer to the vendor's specifications.
