This is the GE-W-38.1-6, a 38.1 mm diameter Germanium Flat Window with a thickness of 6mm, uncoated. The window is sourced from Alkor Technologies, a reputable vendor in the optical industry.
The GE-W-38.1-6 is a type of Window, specifically a Flat Window, which is characterized by its base shape of a Circle. The geometry of this window is defined by its diameter of 38.1mm and a thickness of 6mm.
The material of this window is Germanium, specifically identified as Germanium Burnett. This material is known for its excellent transmission properties, particularly in the infrared region of the spectrum, with a wavelength of 10600nm.
The window has a shape of a Thin Lens, which is a simple lens that has a very small thickness compared to its diameter. This shape is often used in optical systems where the lens's thickness does not significantly affect the optical path.
The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where the natural properties of the material are desired, or where cost is a concern.
