The AL-W-50.8-4 is a 50.8 mm diameter sapphire flat window with a thickness of 4mm, sourced from Alkor Technologies. This window is of the flat variety, designed in a circular base shape, making it suitable for a wide range of applications.
The material of this window is identified as al2o3 mal-1972-n-o, a type of sapphire known for its exceptional hardness, chemical resistance, and thermal stability. These properties make it an ideal choice for applications that require a durable and reliable optical window.
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, or where the introduction of a coating could potentially interfere with the performance of the system.
The window is designed with a thin lens shape, which can be advantageous in applications where a thin, lightweight window is required. The wavelength of this window is 633nm, which is often used in visible light applications.
