The MF-W-38.1x3 is a flat window type optical element, sourced from Alkor Technologies, with a circular base shape and a diameter of 38.1 mm. This window is designed for use in optical systems where a clear aperture is required, and minimal optical power is desired.
The window is made from magnesium fluoride (MgF2), a material with a refractive index of 1.38 and a dispersion of 0.058 at the wavelength of 633 nm. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum, making it suitable for a wide range of optical applications.
The window has a thickness of 3 mm, which is sufficient to provide mechanical rigidity while minimizing optical power. The uncoated surface of the window is ideal for applications where broadband anti-reflection coatings are not required.
