69-672 50mm Dia. x 100mm FL; Coated; Ge Plano-Convex Lens BBAR 8-12µm

The 69-672 is a 50mm diameter, 100mm focal length plano-convex lens, designed for use in the 8-12µm wavelength 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. The plano-convex geometry, where one side is flat and the other is curved, is ideal for a variety of applications, including beam shaping and focusing.

The lens features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, designated as 'edm arcedgermanium81'. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The coating is specifically designed for use in the 8-12µm wavelength range, ensuring optimal performance in this spectral region.

The lens has a center thickness of 4mm and an edge thickness of 2.61mm. The front surface has a radius of curvature of 300.39mm, and the back focal length is 99mm. The lens does not have any inner or outer radii, indicating a simple, two-surface design.
