WSI1501 15 mm Dia. Silicon Round Window; t=1mm Uncoated

The WSI1501 is a circular, flat window made from silicon, with a diameter of 15 mm and a thickness of 1 mm. This window is sourced from Knight Optical and is currently in stock. It is available for purchase through their website, with the catalog number WSI1501.

This optical element is classified as a window, a type of optical component that allows the transmission of light without significant reflection or absorption. The window's base shape is circular, making it suitable for applications where a circular aperture is required.

The material of this window is silicon, specifically silicon sal vil 1957. Silicon is a popular choice for optical components due to its excellent transmission properties, chemical resistance, and mechanical strength.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where a high level of transmission is required, or where the environmental conditions do not necessitate the use of a coating.

The window's geometry is that of a thin lens, which means it has very little curvature. This makes it ideal for applications where a flat surface is required, or where the optical path length needs to be minimized.

The window is designed to operate at a wavelength of 633 nm. This wavelength falls within the visible spectrum, making the window suitable for use in applications involving visible light.
