WMG2504 25 mm Dia. Magnesium Fluoride Round Window; t=5mm Uncoated

The WMG2504 is a 25 mm diameter circular window made from magnesium fluoride, sourced from Knight Optical. This flat window, with a thickness of 5 mm, is designed for use in the visible spectrum, specifically at a wavelength of 633 nm.

The window is uncoated, which means it does not have any additional layers applied to its surface. This can be beneficial in certain applications where maintaining the natural properties of the material is crucial. However, it's important to note that uncoated windows may have higher reflectivity compared to coated ones.

The window's geometry is defined by its diameter and thickness. With a diameter of 25 mm, it provides a substantial aperture while maintaining a manageable size. The thickness of 5 mm ensures structural integrity and resistance to deformation.

This window is classified as a thin lens, indicating its potential use in optical systems where minimal optical power is required. Despite its thinness, it maintains the properties of magnesium fluoride, including its excellent transparency and resistance to environmental factors.
