87-954 50mm Dia. x 100mm FL; Coated; Ge Plano-Convex Lens BBAR 3-12µm
The 87-954 is a 50mm diameter, 100mm focal length plano-convex lens, designed for use in the 3-12µm spectral range. This lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is currently in stock.
The lens is made of Germanium burnett, a material known for its excellent transmission properties in the infrared spectrum. It features a front and back coating of EDM ARCEDGERMANIUM31, a broadband anti-reflection coating that further enhances its performance by reducing surface reflections.
The geometry of the lens includes a 2.61mm edge thickness and a 4mm center thickness. The front surface has a radius of curvature of 300.39mm, resulting in a back focal length of 99mm. The lens does not have an inner or outer radius, indicating a planar back surface.
This lens is a spherical element, which is a common type of lens used in various optical systems due to its simple design and manufacturability. The plano-convex configuration is particularly useful for beam shaping and collimation applications.
