AL-W-90-6 90 mm Dia. Sapphire Flat Window; t=6mm Uncoated

The AL-W-90-6 is a 90 mm diameter Sapphire Flat Window, with a thickness of 6mm, sourced from Alkor Technologies. This window is a type of optical element, specifically designed for use in various optical systems, where it serves as a transparent barrier that allows light to pass through while minimally affecting the optical properties of the system.

The window is made of Sapphire, a material with the chemical formula Al2O3, also known as aluminum oxide. Sapphire is a highly durable and scratch-resistant material, making it an ideal choice for applications that require a high level of optical clarity and robustness. The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties.

The geometry of the window is defined by its diameter and thickness. With a diameter of 90 mm, it is suitable for use in a wide range of optical systems. The thickness of 6mm provides a good balance between mechanical strength and optical performance.

The window is designed in the shape of a thin lens, which is a type of lens with a very small thickness compared to its diameter. This shape allows the window to have minimal impact on the light passing through it, ensuring the highest possible optical quality.

The window is designed to work with a wavelength of 633nm. This wavelength is within the visible light spectrum, meaning the window can be used in systems that work with visible light.
