The GE-W-38.1-5 is a 38.1 mm diameter Germanium Flat Window with a thickness of 5mm, sourced from Alkor Technologies. This window is a type of optical element designed for use in various applications where transmission of infrared light is required.
The Germanium material used in this window is known as germanium burnett. It is specifically designed to transmit light at a wavelength of 10600 nanometers, making it suitable for use in mid-infrared applications.
The window features a flat base shape and a thin lens shape, which is ideal for applications where a flat, transparent surface is needed, but a lens-like effect is also desired. The uncoated nature of this window means that it does not have any additional layers applied to its surface to alter its optical properties.
