AL-W-38.1-3 38.1 mm Dia. Sapphire Flat Window; t=3mm Uncoated

The AL-W-38.1-3 is a 38.1 mm diameter sapphire flat window with a thickness of 3mm, sourced from the reputable vendor 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's base shape is circular, making it suitable for applications where a circular aperture is required. The geometry of the window is defined by its diameter and thickness. With a diameter of 38.1 mm, it provides a substantial aperture for light transmission while maintaining a manageable size for integration into optical systems. The thickness of 3mm ensures rigidity and resistance to deformation, contributing to the overall optical performance of the system.

The material of the window is identified as al2o3 mal-1972-n-o, which is a type of sapphire. Sapphire is known for its exceptional optical properties, including high transparency across a wide range of wavelengths, making it an ideal material for optical windows. It also exhibits excellent mechanical properties, such as high strength, hardness, and thermal shock resistance, ensuring longevity and reliability in various operating conditions.

The window does not have any coating, which means it is uncoated. This may be suitable for applications where no specific coating is required, or where the natural properties of sapphire are sufficient. However, users should be aware that coatings can be applied to enhance the performance of the window, such as anti-reflective coatings to increase transmittance or AR/HR coatings to manage reflections.
