69-671 50mm Dia. x 75mm FL; Coated; Ge Plano-Convex Lens BBAR 8-12µm
The 69-671 is a 50mm diameter, 75mm focal length plano-convex lens, designed for use in the 8-12µm spectral range. This lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from Germanium burnett, a material known for its excellent transmission properties in the infrared spectrum. It features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, further enhancing its performance in the specified wavelength range. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens.
The geometry of the lens includes a 2.61mm edge thickness and a 4mm center thickness. The front surface of the lens has a radius of curvature of 225.29mm, resulting in a back focal length of 74mm. The lens does not have any inner or outer radii, indicating a simple, plano-convex design.
