This is a 520-5385 Magnesium Fluoride Window, a high-quality optical component sourced from EKSMA Optics. With a diameter of 38.1 mm and a thickness of 5 mm, it is designed to provide excellent optical performance.
The window is made of Magnesium Fluoride (MgF2), a material with a refractive index of 1.38 at 1000 nm. This material is known for its excellent transmission properties in the ultraviolet (UV) and infrared (IR) regions of the spectrum, making it suitable for a wide range of optical applications.
The window features a flat design, which helps to minimize optical aberrations and distortions. It is uncoated, which means it does not have any additional layers of anti-reflective or other coatings. This can be beneficial in certain applications where a bare substrate is required.
The window is available for purchase directly from the EKSMA Optics website, where you can find more detailed specifications and pricing information. Please note that the status of the weblink was valid at the time of data collection, indicating that the product is currently in stock.
