11-920 12.5 x 12.5 mm UVFS Protective Flat Window; t=2 mm MgF2 400-700nm

This 11-920 protective flat window, sourced from Edmund Optics, is a high-quality optical component designed for use in a wide range of applications. The window features a base shape of 12.5 x 12.5 mm, making it suitable for use in systems where a small, rectangular window is required.

The window is 2 mm thick, providing a robust and durable barrier that can withstand the rigors of regular use. It is made from UVFS, a material with the ID 1965, which is known for its excellent optical properties and resistance to environmental factors.

The window is coated with MgF2 on both the front and back surfaces, following the standard curve. This coating enhances the window's performance by reducing reflection and increasing transmission, particularly in the 400-700nm wavelength range. The coating also provides protection against environmental contaminants, ensuring the window maintains its performance over time.

The window is shaped as a thin lens, which is a type of lens with a short focal length and a small amount of optical power. This shape is often used in applications where a wide field of view is required, or where the lens needs to be as small and lightweight as possible.
