561-6275 25.4 mm Dia. x 1000 mm FL Plano-Convex Lens AR 10600nm

The 561-6275 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by having one side flat and the other side curved. This lens, with a diameter of 25.4 mm, is designed for use in the infrared spectrum, specifically at a wavelength of 10600nm.

The lens has an effective focal length (EFL) of 1000 mm, which is the distance from the lens's center to the point at which light rays converge. The lens's edge thickness is 2.5 mm, and it has a front radius (R1) of 1400 mm. The lens's inner and outer radii are both 0 mm, indicating that the lens is a simple Plano-Convex design.

The lens is made of Zinc Selenide (ZnSe), a material with excellent optical properties in the infrared spectrum. The lens is coated with EKS ZnSe AR 10600, a specialized anti-reflective coating designed for use at a wavelength of 10600nm. This coating helps to reduce surface reflections, improving the lens's performance in its intended application.

The lens is available from EKSMA Optics, a reputable vendor of optical components. According to the vendor's website, the lens is currently in stock, indicating that it is readily available for purchase and use. The lens's webpage also provides additional information and resources, including technical specifications and related products.
