WBMA-25C02-10-550 25 mm Dia. N-BK7 Round AR coated Flat Window; t=2 mm 400-700nm

The WBMA-25C02-10-550 is a high-quality optical window from OptoSigma, a leading vendor in the optical industry. This window, designed for use in the visible light spectrum, features a flat, circular shape with a diameter of 25 mm and a thickness of 2 mm.

The window is made from N-BK7, a popular glass type known for its excellent optical properties. N-BK7, also known as Borosilicate Crown Glass, is a borosilicate glass with a low coefficient of thermal expansion, making it resistant to thermal shock. It also has a high Abbe number, which reduces chromatic aberration, making it ideal for use in a wide range of optical applications.

The WBMA-25C02-10-550 is coated with an anti-reflection (AR) coating on both the front and back surfaces. This coating, denoted as "opt m", is designed to minimize reflection and increase transmission in the 400-700 nm range. The AR coating ensures that the maximum amount of light passes through the window, reducing losses and improving the overall performance of the optical system.

The window is classified as a "Thin Lens" shape, indicating that it has a very low curvature. This makes it suitable for use as a flat window, where minimal optical distortion is required.
