SI-W-25.4-3 25.4 mm Dia. Silicon Flat Window; t=3mm Uncoated

This is a Silicon Flat Window, sourced from Alkor Technologies, with a diameter of 25.4 mm and a thickness of 3 mm. The item is a circular 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. The silicon material used in this window is identified as "silicon sal vil 1957".

The window has a wavelength of 633 nm, which is typically used in red laser systems. This makes it suitable for applications that require the transmission of red light, such as in laser-based measurement systems, spectroscopy, or optical communication systems.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be advantageous in certain applications where the user does not want to alter the optical properties of the light beam, or where cost is a concern. However, it should be noted that uncoated windows may have higher surface reflections and may not be as resistant to environmental conditions as coated windows.
