89-570 50 mm Dia. Germanium Protective Flat Window; t=3 mm BBAR 3-5µm

The 89-570 is a 50 mm diameter Germanium Flat Window, with a thickness of 3 mm, designed for optimal performance in the 3-5 µm wavelength range. This component is sourced from Edmund Optics, a trusted vendor known for its high-quality optical elements.

The window features a Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces, specifically the EDM ARCEDGERMANIUM35 coating. This coating is designed to minimize reflection and optimize transmission across the specified wavelength range. The BBAR coating ensures high-transmission performance, making this window ideal for applications that require maximum light transmission.

The window is designed in a Thin Lens shape, which is a simple lens where the thickness is much less than the radius of curvature. This design ensures minimal optical aberration, providing clear and accurate optical transmission.

The window is made of Germanium, a material known for its excellent transmission properties in the infrared region of the spectrum. Germanium is also highly resistant to environmental factors, making it suitable for use in various conditions.
