The SI-W-12.7-1 is a 12.7 mm diameter Silicon Flat Window with a thickness of 1mm, sourced from the reputable vendor Alkor Technologies. This window is a type of optical element, specifically designed for use in various optical systems.
The window is made of Silicon, identified as "silicon sal vil 1957" in the Material ID, a material known for its excellent optical properties and durability. The window's base shape is circular, making it suitable for a wide range of applications where a circular aperture is required.
The window is uncoated, meaning it does not have any additional layers of material applied to its surface to alter its optical properties. This can be beneficial in certain applications where a bare silicon surface is desired.
The window is designed in the shape of a thin lens, which can provide some focusing capabilities, depending on the specific application. The wavelength of this window is 633 nanometers, which is within the visible light spectrum.
