The 11-930 is a circular, flat window with a diameter of 100 mm and a thickness of 8 mm. This window is made from UVFS, a material with the ID UVFS Mal-1965. The window is coated with MgF2 on both the front and back surfaces, providing a standard curve within the wavelength range of 400-700nm, with a central wavelength of 587.6nm. This coating enhances the window's performance in terms of transmission and reflection, making it suitable for a wide range of optical applications. The window is designed in the shape of a thin lens, which is ideal for applications that require minimal optical distortion. The window is currently in stock and available for purchase from Edmund Optics, as indicated by the valid weblink status.
