11-877 25 mm Dia. UVFS Round Protective Flat Window; t=2 mm Uncoated

The 11-877 is a 25 mm diameter, 2 mm thick uncoated flat window made from UVFS material, sourced from Edmund Optics. This window is designed to protect optical systems from environmental hazards while minimally affecting the light path.

The UVFS material, also known as UV-grade fused silica, is a high-purity silica glass with excellent transmission properties in the ultraviolet region. It is characterized by a low coefficient of thermal expansion, making it resistant to thermal shock and dimensional changes over a wide temperature range. This material also exhibits high resistance to chemical attack and radiation damage, ensuring longevity and reliability in various applications.

The window's flat geometry ensures a planar surface with minimal distortion, making it suitable for use in imaging systems, beam delivery, or as a protective cover for sensitive optical components. The window's thin profile minimizes the introduction of aberrations and reduces weight, making it an ideal choice for applications where space and weight are critical factors.

The uncoated surface of the window provides a broadband anti-reflective performance, maximizing transmission and minimizing losses due to surface reflections. However, for applications requiring specific reflection or transmission characteristics, various coatings can be applied to enhance performance.
