The 520-5253 is a circular, flat window made from Magnesium Fluoride (MgF2) with a diameter of 25.4 mm and a thickness of 3 mm. This window, offered by EKSMA Optics, is uncoated and designed to be used in the ultraviolet and infrared spectrum, specifically at a wavelength of 1000 nm.
The window is categorized as a thin lens due to its minimal thickness relative to its diameter. This feature makes it an ideal choice for applications that require minimal optical interference or distortion. The uncoated nature of the window means it does not have any additional anti-reflective or protective coatings, which can be beneficial in certain applications where such coatings may interfere with the desired optical properties.
