SI-W-50.8-4 50.8 mm Dia. Silicon Flat Window; t=4mm Uncoated

The SI-W-50.8-4 is a circular silicon flat window, 50.8 mm in diameter and 4 mm in thickness, sourced from Alkor Technologies. This window is a type of optical element, specifically designed for use in various optical systems.

The window is made of silicon, a material known for its excellent mechanical and thermal properties, making it suitable for use in harsh environments. The silicon material used in this window is identified as "silicon sal vil 1957", indicating its specific composition and properties.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface to alter its optical properties. This can be beneficial in situations where the user wants to minimize reflections or other optical effects that can be introduced by coatings.

The window is designed in the shape of a thin lens, which can help to focus or disperse light in certain applications. However, as a flat window, it does not introduce any curvature or focusing power to the light passing through it.

The window is designed to work with light of a wavelength of 633 nm. This wavelength is commonly used in various applications, including laser systems and spectroscopy.
