This is a Silicon Flat Window, sourced from Alkor Technologies, with a diameter of 25.4 mm and a thickness of 4 mm. The item is a circular, flat window, designed with a thin lens shape, and is uncoated.
The Silicon Flat Window is a type of optical window, which is a simple optical component that primarily serves to provide a passage for the light beam. It is made of silicon, a semiconductor material with excellent mechanical and thermal properties, making it suitable for various applications.
The window has a diameter of 25.4 mm, which is a common size in optical components, ensuring compatibility with various systems. The thickness of 4 mm provides sufficient structural integrity while minimizing optical distortion.
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 spectral properties of the light passing through the window.
