65-869 50 mm Dia. Fused Silica High Power Laser Line Flat Window; t=3 mm Laser V-Coat 1064nm

This 65-869 optical window, sourced from Edmund Optics, is a 50 mm diameter Fused Silica window with a thickness of 3 mm, specifically designed for high power laser applications at a wavelength of 1064nm. The window features a Laser V-Coat 1064nm coating on both the front and back surfaces, providing superior laser damage resistance and high transmission at the specified wavelength.

The window is of the Flat Window sub-type, part of the Window type category, and has a base shape of Circular. It is designed with a Thin Lens shape, making it suitable for a wide range of optical systems. The window's geometry, defined by its 50 mm diameter and 3 mm thickness, ensures excellent optical performance while maintaining a compact and lightweight design.

The Fused Silica material, identified as UVFS MAL-1965, offers excellent transmission across a broad spectrum, from the ultraviolet to the infrared regions. It also exhibits high resistance to thermal shock and environmental stress, making it an ideal choice for high power laser applications.

The window's coating, Laser V-Coat 1064nm, is a vacuum-deposited coating that provides superior laser damage resistance and high transmission at the specified wavelength. This coating is designed to withstand the rigors of high power laser applications, ensuring reliable and consistent performance.
