47-835 40 mm Dia. UVFS Round Protective Flat Window; t=4 mm Uncoated

The 47-835 is a 40 mm diameter, 4 mm thick uncoated flat window made from UVFS (UV Fused Silica) material, sourced from Edmund Optics. This window is designed as a protective component in optical systems, providing a flat interface for beam transmission while minimizing optical losses.

UVFS, also known as synthetic fused silica, is a high-purity silica glass with excellent optical properties. It offers a low coefficient of thermal expansion, high thermal shock resistance, and exceptional transmission in the deep UV, visible, and near-IR regions. The uncoated surface of this window ensures high laser damage threshold and low auto-fluorescence, making it suitable for applications that require high optical quality and precision.

The window's thin lens shape and circular geometry enable easy integration into various optical systems. With a 40 mm diameter and 4 mm thickness, this window provides excellent mechanical stability and rigidity, ensuring reliable performance even in demanding environments.

For those seeking a high-performance, uncoated flat window, the 47-835 is an excellent choice. Its compatibility with a wide range of wavelengths, coupled with its robust construction, makes it a versatile component in numerous applications, such as imaging, beam delivery, and laser systems.
