WQF4000 40 mm Dia. Quartz Round Window; t=2mm Uncoated

The WQF4000 is a 40 mm diameter Quartz Round Window with a thickness of 2 mm, sourced from Knight Optical. This window is a flat, circular optical component designed for use in various applications. It is made of quartz, specifically silicon dioxide (SiO2), a material known for its high transparency and durability.

The window's 40 mm diameter makes it suitable for applications requiring a larger aperture, while its 2 mm thickness provides sufficient structural integrity without compromising optical performance. The uncoated surface ensures minimal reflection, making it ideal for applications where maximum transmission is required.

This window is designed with a thin lens shape, which minimizes optical aberrations and distortions. It is intended for use at a wavelength of 633 nm, although its high transparency across a broad spectrum makes it versatile for various applications.

The WQF4000 is currently in stock and available for immediate purchase from Knight Optical's website. Its catalog number is WQF4000, and it can be found at the following link: https://www.knightoptical.com/stock/default/ir-quartz-window-40mmdiax2mmthk.html
