WG31050-E 1in Dia. AR Coated; Sapphire Broadband Precision Window; t=5 mm 2-5µm

The WG31050-E is a high-quality flat window, circular in base shape, and sourced from the reputable vendor Thorlabs. This window, with a diameter of 1 inch (25.4 mm), is designed for use in optical systems that require precision and durability.

The window's material is sapphire, identified as sapphire ow mal-1972 in the Thorlabs material catalog. Sapphire is a highly desirable material in optical applications due to its excellent properties, such as its high transparency across a broad spectrum, including the visible and near-infrared regions, and its exceptional hardness, which provides excellent scratch resistance.

The WG31050-E features a thickness of 5 mm and is coated with an anti-reflection (AR) coating, specifically the tho e1sapphir2000500 coating, on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, thereby enhancing the performance of the optical system in which it is used.

The window's shape is thin lens, which suggests that it may have some slight focusing power, although this is not its primary function. The window is designed to work optimally at a wavelength of 633 nm, although its broadband characteristics ensure it can be used across a wider spectral range.

According to the vendor's information, the WG31050-E is currently in stock, making it readily available for immediate use in your optical projects. For more detailed information, you can refer to the vendor's product webpage at https://www.thorlabs.com/thorproduct.cfm?partnumber=WG31050-E1.
