05QW20-1 12.5 mm Dia. UVFS High Energy Laser Line Optical Flat Window; t=3mm V-Coat 1064nm

The 05QW20-1 is a high-quality optical flat window designed for use with high energy lasers, specifically tuned for the 1064nm wavelength. This window is manufactured by MKS/Newport, a trusted name in the optical industry, and is available for purchase directly from their website.

This window is circular in shape, with a diameter of 12.5mm and a thickness of 3mm, making it a thin and lightweight option for your optical system. The material used for this window is UVFS, which is a specialized material with a Material ID of 1965. This material is known for its durability and resistance to high energy laser damage, making it an ideal choice for demanding optical applications.

The 05QW20-1 features a new V-coat on both the front and back surfaces. This coating is specifically designed for the 1064nm wavelength, providing excellent transmission and minimal reflection. The V-coat is a broadband anti-reflection coating that is applied to both surfaces of the window, ensuring maximum transmission and minimal loss of light.

In terms of geometry, this window is a flat window, meaning it does not have any curvature. This is ideal for applications where a flat surface is required, such as in beam delivery systems or laser resonators. The window is also classified as a Thin Lens, indicating that it has minimal optical power and will not significantly affect the focusing or divergence of a beam.
