AL-W-25.4-3 25.4 mm Dia. Sapphire Flat Window; t=3mm Uncoated

The AL-W-25.4-3 is a 25.4 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 where transparency and durability are paramount.

The window is made of Sapphire, a material with the chemical formula Al2O3, also known as aluminum oxide. Sapphire is a highly durable material, known for its hardness, second only to diamond on the Mohs scale. This hardness makes it resistant to scratches and abrasions, ensuring a clear view even in harsh environments.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where the natural properties of sapphire are desired, such as its high transparency to visible light and its resistance to environmental factors like temperature and humidity.

The window has a flat shape, which is ideal for applications where a flat, undistorted view is required. This makes it suitable for use in various optical systems, including cameras, telescopes, and other precision instruments.

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