LA9953-E3 25.4 mm Dia. Germanium Plano-Convex Lens; EFL=500mm 7-12µm

This is a LA9953-E3 25.4 mm Dia. Germanium Plano-Convex Lens, specifically designed for use with a wavelength of 10600 nm and featuring an effective focal length (EFL) of 500mm. The lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.

The lens is spherical in shape, with a base shape of a circle. It has a diameter of 25.4 mm and a thickness at the edge of 2 mm. The thickness at the center of the lens is slightly more, at 2.1 mm. The lens's inner radius is 0, while the outer radius is also 0, indicating a plano-convex design.

The LA9953-E3 lens is made from Germanium Burnett, a specific type of germanium known for its excellent optical properties. The lens is coated on both the front and back with tho e3gearc700012000, a coating that enhances its performance in the specified wavelength range of 7-12 µm.

This lens is a versatile and high-performance option for applications that require a plano-convex lens with a long effective focal length and a specific wavelength range. It is currently in stock, according to the vendor's website, making it a readily available solution for your optical needs.
