36-938 50 mm Dia. UVFS Round Protective Flat Window; t=1 mm UV-AR 250-425nm

The 36-938 is a 50 mm diameter, 1 mm thick flat window made from UVFS material with a standard UV-AR coating on both sides. This window is designed to protect optical systems from environmental factors while minimizing unwanted reflections and maintaining high transmission in the UV-AR range of 250-425 nm.

The UVFS material, also known as UV-grade fused silica, is a high-purity silica glass with excellent transparency in the UV range. It is characterized by a low coefficient of thermal expansion, making it suitable for applications involving temperature fluctuations. The 1 mm thickness provides a good balance between mechanical strength and light weight, ensuring durability without compromising optical performance.

The window features a standard UV-AR coating on both the front and back surfaces. This coating is designed to reflect as little UV light as possible, thereby maximizing transmission. The coating curve is the EDM UV STD curve, which is a common standard in the industry. This coating not only enhances the window's performance in the UV range but also provides some protection against environmental contaminants.

The 36-938 is shaped as a thin lens, which is a simple optical component with two spherical surfaces. This shape allows the window to be easily integrated into various optical systems. It is available from Edmund Optics, a leading supplier of optical components. According to the vendor, the window is currently in stock, ensuring quick delivery for your optical project needs.
