39-280 38.1 mm Dia. Float Glass High Efficiency Protective Flat Window; t=1 mm BBAR 425-700nm

This 39-280 optical window, sourced from Edmund Optics, is a high-efficiency protective flat window designed for optimal performance in a wide range of optical applications. The window boasts a base shape of Circular, with a generous diameter of 38.1 mm and a thickness of 1 mm, providing a robust and stable platform for various optical setups.

The window is crafted from soda lime ru clear, a material known for its excellent optical properties and durability. This material ensures high light transmission and resistance to environmental factors, making it an ideal choice for applications that require a high level of optical clarity and stability.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, specifically designed for the wavelength of 587.6 nm. This coating significantly reduces reflection, thereby enhancing light transmission and improving the overall performance of the optical system.

The window's geometry is that of a Thin Lens, which means it has a very small curvature, making it virtually flat. This feature makes it suitable for applications that require a flat surface, such as beam splitters or as a protective window in front of sensitive optical components.
