This is the GE-W-25.4-3, a 25.4 mm diameter Germanium Flat Window with a thickness of 3mm, uncoated and sourced from Alkor Technologies. The item is a Window type optical component, specifically a Flat Window, designed with a Circular base shape.
The Germanium material of this window is identified as "germanium burnett" in the Material ID. It is designed to operate at a wavelength of 10600 nanometers, making it suitable for infrared applications. The window's geometry is defined by its diameter and thickness, with the former being 25.4 mm and the latter being 3 mm.
The window's shape is defined as a Thin Lens, although it does not have any lens properties. This could be useful in applications where a flat, transparent window is required, but a lens shape is needed for alignment or mounting purposes.
The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This could be beneficial in applications where such coatings are not required or could interfere with the operation of the system.
