This is a CaF2-W-10x0.8 10 mm Dia. CaF2 Flat Window, a high-quality optical component sourced from Alkor Technologies. The window, which has a flat base shape, is circular with a diameter of 10 mm and a thickness of 0.8 mm, making it a thin and lightweight option for various optical applications.
The window is made of Calcium Fluoride (CaF2), a material with the Mal-1963 ID, which is known for its excellent optical properties, including a high transmission rate in the ultraviolet, visible, and near-infrared regions of the spectrum. This specific window is designed for use with a wavelength of 633 nm, making it suitable for a wide range of applications that use this wavelength.
The window has a shape described as a thin lens, which suggests that it may have some light-bending properties, although this is not explicitly stated in the provided data. What is clear, however, is that the window is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
According to the vendor's website, this item is currently in stock, and more information about it can be found at http://www.alkor.net/CaF2_windows.html. This makes it a readily available option for those in need of a high-quality CaF2 window.
