The FSW14AR.10 is a 20 mm diameter Flat Window, part of the Window product range from MKS/Newport. This particular model is designed for use with UVFS material, specifically UVFS Mal-1965, and features a thickness of 2 mm.
The window is designed to operate within the wavelength range of 250-450nm, making it suitable for applications that require ultraviolet light transmission. The front and back of the window are coated with new AR-10 fromfigure, a type of anti-reflective coating that helps to minimize light loss due to reflection.
The window is shaped as a Thin Lens, which is a lens with a very small focal length compared to its diameter. This shape is often used in optical systems where a wide field of view is required, or where the optical system needs to be as compact as possible.
The FSW14AR.10 is currently in stock and more information about this product can be found on the MKS/Newport website.
