The CVI PW1-2025-UV is a high-quality optical window from CVI Laser Optics, designed for use in laser systems and other applications where precise optical performance is required. This window features a flat design with a diameter of 50.8 mm and a thickness of 6.35 mm, making it suitable for a wide range of applications.

The window is made from UVFS, a material with a high damage threshold and excellent transmission properties in the ultraviolet region of the spectrum. This makes it ideal for use in UV laser systems, where high transmission and resistance to damage are essential. The material is identified as "UVFS Mal- 1965" in the manufacturer's catalog.

The PW1-2025-UV is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in some applications, as it reduces the risk of coating damage and simplifies cleaning and maintenance. However, it may result in higher reflective losses, which should be taken into account when designing the optical system.
