The WG41050-C is a precision window made from UVFS material with a diameter of 1 inch (25.4 mm) and a thickness of 5 mm. This window is designed for broadband use, specifically for wavelengths between 1050 and 1700 nm. The window features an anti-reflection coating on both the front and back surfaces, which is identified as 'tho c bbar'. This coating enhances transmission and reduces reflection, making it ideal for applications that require high-transmission windows. The window's shape is defined as 'Thin Lens', which suggests that it may have some slight curvature, although this is not explicitly stated in the provided data. The window is sourced from Thorlabs, a reputable vendor in the optical industry, and is currently in stock, as indicated by the 'weblink status'.
