WG11010-A Dia:1in N-BK7 Broadband Precision Window; t=1 mm ARC 350-700nm

The WG11010-A is a high-quality, broadband precision window offered by Thorlabs. This window, designed for general-purpose use, is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The window has a diameter of 1 inch (25.4 mm) and a thickness of 1 mm, making it a versatile and compact option for various applications.

The WG11010-A features an anti-reflection (AR) coating on both the front and back surfaces, specifically designed for the wavelength range of 350-700 nm. This coating reduces reflection, thereby increasing transmission, which is crucial for applications where maintaining high light levels is essential. The coating also helps minimize surface scattering, contributing to improved image quality and system performance.

The window's shape is designed as a thin lens, which can be beneficial in certain applications where a lens-like component is required. However, it's important to note that this window does not have any focusing power.
