48-859 203.2 mm Dia. Float Glass High Efficiency Protective Flat Window; t=3 mm BBAR 425-700nm

This 48-859 optical window, sourced from Edmund Optics, is a high-efficiency protective flat window designed for optimal performance in a wide range of applications. With a diameter of 203.2 mm and a thickness of 3 mm, it is a substantial and robust component, ideal for use in systems that require durable and transparent optical elements.

The window is made from soda lime, a common and reliable material in the optical industry, known for its clarity and durability. The window's flat base shape ensures a uniform and consistent optical path, reducing distortions and aberrations that can occur with curved or irregular surfaces.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, specifically designed for the wavelength range of 425-700nm. This coating significantly reduces reflective losses, improving transmission and enhancing the overall efficiency of the optical system. The coating is identified by the vendor code "edm pid1919hearced39".

The window's geometry is that of a thin lens, suggesting that it may have some slight focusing properties, although this is not its primary function. The lens shape may be beneficial in certain applications where a slight convergence or divergence of light is desired.
