75 mm Diameter Zinc Selenide Protective Flat Window with BBAR Coating
The 48-855 is a 75 mm diameter Zinc Selenide (ZnSe) flat window with a thickness of 6 mm, designed for protective optical applications. This window is sourced from Edmund Optics and is available for immediate purchase, as indicated by its "in stock" status on the vendor's website.
The window features a Broadband Anti-Reflective (BBAR) coating on both the front and back surfaces, specifically designed for the ZnSe material in the 3-12 μm wavelength range. This coating significantly reduces surface reflections, enhancing the overall transmission of the window.
The window's geometry is defined by a 75 mm diameter and a 6 mm thickness, making it suitable for applications that require a large aperture and a moderate thickness for structural integrity. The window's base shape is circular, a common geometry in optical systems due to its ease of alignment and integration.
The window is categorized as a "Thin Lens" shape, indicating that its thickness is significantly smaller than its diameter, allowing it to be treated as a thin lens in most optical systems. This simplifies optical design and analysis, making the window a versatile component in various optical systems.
