89-568 50 mm Dia. Germanium Protective Flat Window; t=1 mm BBAR 3-5µm
The 89-568 is a 50 mm diameter Germanium Flat Window, with a thickness of 1 mm, designed for optimal performance in the 4000 nm wavelength range. This Window is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for immediate purchase, as indicated by its "in stock" status on the vendor's website.
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 combination of the Germanium material and the BBAR coating makes this Window an ideal choice for applications that require high transmission and excellent optical quality in the infrared spectrum.
The Window's geometry is defined by its 50 mm diameter and 1 mm thickness, making it a suitable choice for applications that require a thin, lightweight, and durable optical component. The Window's base shape is circular, which is a common and versatile shape in optical systems due to its ease of alignment and integration.
