The 45-568 is a circular, flat window with a diameter of 38.1 mm and a thickness of 1 mm. This window is sourced from Edmund Optics and is made of high-quality sapphire, identified by the Material ID "al2o3 mal-1972-n-o".
Sapphire, known for its exceptional durability and resistance to scratching, makes this window an ideal choice for protective applications. The window is uncoated, which means it does not have any additional layers to alter its optical properties. This can be beneficial in situations where maintaining the window's natural optical characteristics is crucial.
The window is designed to operate at a wavelength of 587.6 nm, which is in the visible light spectrum. Its "Thin Lens" shape suggests that it has minimal optical power, making it suitable for applications that require a clear, unaltered view of the optical path.
The window's web links are valid and indicate that it is currently in stock, making it readily available for immediate use.
