89-567 40 mm Dia. Germanium Protective Flat Window; t=4 mm BBAR 3-5µm

The 89-567 is a 40 mm diameter Germanium Flat Window, featuring a thickness of 4 mm and equipped with Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces. This component is sourced from Edmund Optics, a reputable vendor in the optical industry.

The window's base shape is circular, making it suitable for a wide range of applications that require a protective, transparent optical element. The geometry of the window includes a diameter of 40 mm and a thickness of 4 mm, providing a robust and stable platform for optical systems.

The window is made of Germanium burnett, a material known for its excellent optical properties, including high refractive index and low absorption. This makes it an ideal choice for applications that require high transmission and minimal distortion.

The BBAR coating on both surfaces of the window is designed to reduce reflection and increase transmission over a broad spectrum, specifically from 3 to 5 µm. This coating enhances the window's performance in the infrared region, making it suitable for applications such as thermal imaging, spectroscopy, and other infrared-based technologies.

The window is shaped as a thin lens, which can provide additional functionality in certain applications. However, its primary role is to protect the optical system from environmental factors such as dust, moisture, and other contaminants.

The window is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
