AL-W-76.2-3 76.2 mm Dia. Sapphire Flat Window; t=3mm Uncoated

The AL-W-76.2-3 is a 76.2 mm diameter Sapphire Flat Window, with a thickness of 3mm, 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 Sapphire, a material with the chemical formula Al2O3, and is identified as 'mal-1972-n-o' in the Material ID. Sapphire is known for its exceptional hardness, second only to diamond, making it highly resistant to scratches and abrasions. It also has a high melting point and excellent thermal shock resistance, making it suitable for high-temperature applications.

The window is designed in a flat shape, which is ideal for applications that require minimal optical distortion. The geometry of the window includes a diameter of 76.2 mm and a thickness of 3 mm. The flat shape and the specified thickness ensure the window's rigidity and stability within the optical system.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be beneficial in applications where the user does not want to alter the window's inherent optical properties. However, it is important to note that uncoated windows can be more susceptible to environmental factors such as dust and moisture.

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