65-867 50 mm Dia. Fused Silica High Power Laser Line Flat Window; t=3 mm Laser V-Coat 355nm

The 65-867 is a high-performance flat window designed for use with 355nm lasers, offering exceptional optical clarity and durability. Manufactured by Edmund Optics, this circular window boasts a diameter of 50mm and a thickness of 3mm, making it an ideal solution for applications requiring precise, distortion-free laser transmission.

The window is crafted from UVFS fused silica, a material renowned for its exceptional transparency across a wide spectral range, including the ultraviolet region. This ensures minimal absorption and scattering of the laser beam, thereby maximizing energy efficiency and reducing the risk of thermal damage.

Both the front and back surfaces of the window are coated with Edmund Optics' Laser V-Coat 355, a highly reflective coating specifically designed for 355nm lasers. This coating enhances the window's laser damage threshold, providing superior protection against laser-induced damage and ensuring long-term reliability.

The window's thin lens shape further contributes to its performance, minimizing spherical aberration and other optical distortions that can degrade laser beam quality. This makes the 65-867 an excellent choice for applications requiring high-precision laser alignment and focusing.
