10Q20RAR.L 25.4 mm Dia. UVFS Antireflection o-Texture Surface Parallel Optical Flat Window; t=4 mm 500-1100nm

The 10Q20RAR.L is a high-quality optical window, specifically designed for use in the UV-FS (Ultraviolet to Far-Infrared) spectral range, offering excellent transparency from 500 to 1100nm. This window is sourced from the reputable vendor, MKS/Newport, and is available for immediate purchase from their website.

This circular window boasts a diameter of 25.4mm and a thickness of 4mm, making it a robust and reliable choice for various optical applications. The window is made from UVFS material, which is known for its superior optical properties and durability.

The 10Q20RAR.L features an antireflection coating on both the front and back surfaces, enhancing its transmission capabilities and reducing unwanted reflections. The coating, new rarlar5001100, is specifically designed for use in the UV-FS range, ensuring optimal performance across the window's spectral range.

The window's shape is classified as a Thin Lens, indicating its potential use in focusing or collimating light. However, its primary function remains that of a window, providing a clear, undistorted view of the optical path while minimizing losses due to reflection or absorption.
