WSI2501 25.4 mm Dia. Silicon Round Window; t=1mm Uncoated

The WSI2501 is a 25.4 mm diameter silicon round window with a thickness of 1 mm, sourced from Knight Optical. This window is a flat, circular optical component designed for use in various applications. The window's thin lens shape and uncoated surface make it a versatile option for a wide range of optical systems.

The window's material is silicon, specifically identified as "silicon sal vil 1957" in the material database. Silicon is a popular choice in optical applications due to its excellent mechanical properties, chemical resistance, and transparency in the visible spectrum. The window's thickness of 1 mm provides a good balance between mechanical strength and light transmission.

The window's diameter of 25.4 mm is a standard size, making it compatible with many optical systems and components. The uncoated surface of the window means it does not have any additional layers that could affect its optical properties. However, it may be more susceptible to contamination and scratching compared to coated surfaces.

This window is designed to work with a wavelength of 633 nm, which is within the visible light spectrum. It is in stock and available for immediate purchase from Knight Optical's website.
