WHF2500-AU1 25 mm Dia. UVFS Round Window; t=3mm AR 248-400nm

The WHF2500-AU1 is a 25 mm diameter UVFS (UltraViolet Fused Silica) round window with a thickness of 3mm. This optical component is sourced from Knight Optical, a reputable vendor known for its high-quality optical elements. The window is designed with Anti-Reflection (AR) coating, optimized for the ultraviolet spectrum between 248-400nm, making it an ideal choice for applications that require high transmittance in the UV range.

The window is defined by its flat, circular geometry, which is often used in various optical systems due to its simplicity and versatility. The thin lens shape of the window allows for minimal optical aberrations, ensuring the integrity of the light passing through. The window's 3mm thickness provides sufficient mechanical strength while maintaining a low profile in the optical system.

The AR coating on both the front and back surfaces of the window reduces reflection and increases transmittance, enhancing the performance of the optical system. This coating is specifically designed for the UV range, ensuring optimal performance in applications such as UV spectroscopy, UV laser systems, and other UV-based optical systems.
