WZN1911 19 mm Dia. Zinc Sulphide Multispectral (clear) Round Window; t=1mm Uncoated

The WZN1911 is a high-quality, multispectral window offered by Knight Optical. This window, designed for general-purpose use, boasts a 19 mm diameter and a thickness of 1mm, making it a versatile and practical choice for various applications.

The window is made from Zinc Sulphide (ZNS), a material known for its excellent optical properties. Zinc Sulphide is a wide bandgap semiconductor with a high refractive index, making it an ideal material for optical windows. The ZNS Debenham variant used in this window ensures high transparency and durability.

The WZN1911 is designed to be a flat window, which means it has a planar surface on both sides. This design is ideal for applications where a flat, undistorted view is required. The window's geometry is defined by its diameter and thickness, ensuring a precise fit in your optical system.

The window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain optical properties, an uncoated window offers simplicity and versatility. It is suitable for a wide range of wavelengths, including the 10600 nm specified in the item data.

The window's shape is defined as a thin lens, indicating that it has minimal optical power. This makes it ideal for applications where you need to minimize optical distortion and maintain the integrity of the light path.
