69-669 25mm Dia. x 250mm FL; Coated; Ge Plano-Convex Lens BBAR 8-12µm

This is a 25mm diameter, 250mm focal length plano-convex lens, designed for use in the 8-12µm wavelength range. The lens is sourced from Edmund Optics, a leading provider of optical components.

The lens is made from Germanium Burnett, a material known for its high refractive index and transparency in the infrared region. The plano-convex geometry, where one side is flat and the other is curved, is ideal for applications that require a high level of focusing power.

The lens features a broadband anti-reflection (BBAR) coating on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the lens. The coating is applied using Edmund Optics' ARC EDGE technology, ensuring uniform coverage and high durability.

The lens has a center thickness of 3mm and an edge thickness of 2.9mm. The inner and outer radii are 0mm, indicating a flat inner surface and a curved outer surface. The effective focal length (EFL) is 250mm, and the back focal length (BFL) is 249.25mm.
