20QW20-3 50 mm Dia. UVFS High Energy Laser Line Optical Flat Window; t=3mm V-Coat 355nm

The 20QW20-3 is a high-quality optical flat window designed for use with high energy lasers, specifically tuned for the 355nm wavelength. This window is manufactured by MKS/Newport, a renowned vendor in the optical industry, and is available for purchase directly from their website.

This window is circular in shape with a diameter of 50mm and a thickness of 3mm, making it a robust and durable option for various optical applications. The material used for this window is UVFS Mal-1965, a specialized material known for its excellent optical properties and resistance to high energy laser damage.

The 20QW20-3 features a new V-coat 355nm coating on both the front and back surfaces. This coating is specifically designed to enhance the window's performance at the 355nm wavelength, providing improved transmission and reduced reflection. The coating is applied uniformly across the entire surface of the window, ensuring consistent performance and reliability.

The window is shaped as a thin lens, which can be beneficial in certain optical systems where minimal optical path length distortion is required. This feature, combined with its robust construction and high-quality coating, makes the 20QW20-3 an ideal choice for applications that require a high-performance optical window in the UV range.
