68-737 25 mm Dia. Germanium Protective Flat Window; t=3 mm Uncoated

The 68-737 is a 25 mm diameter Germanium Protective Flat Window with a thickness of 3 mm, sourced from the reputable vendor, Edmund Optics. This window is uncoated, making it suitable for various applications where specific coating requirements may not be necessary.

The window is designed in a flat format, which is ideal for applications that require minimal optical distortion. Its circular base shape ensures easy integration into various systems. The geometry of this window is defined by its 25 mm diameter and 3 mm thickness, providing a robust and reliable optical solution.

The material of this window is Germanium, specifically identified as "germanium burnett" in the item data. Germanium is known for its excellent transmission properties in the infrared region of the spectrum, making this window an ideal choice for applications that operate within this range, such as thermal imaging or night vision systems. The specified wavelength for this window is 587.6 nm, which falls within the visible light spectrum.

The window is shaped as a thin lens, indicating its minimal curvature, further reducing optical distortion. The absence of a coating on this window makes it versatile and compatible with a wide range of optical systems, as it does not introduce additional reflective properties that could interfere with the performance of the overall system.
