110-5111E 12.7 mm Dia. x 75 mm FL; Uncoated; Plano-Convex Lens

The 110-5111E is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 75 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for their high-quality optical components. The lens is made of CAF2 (MgF2) material, specifically the Mal-1963 variant, which is well-suited for various applications due to its excellent optical properties.

The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 2 mm, while the center thickness is 2.6 mm. The lens's effective focal length (EFL) is 75 mm, and its radius of curvature (R1) is 31.4 mm. The lens does not have any coating, which means it is uncoated.

This lens is a Spherical lens, which is a type of lens that has surfaces that are parts of spheres. The term "spherical" comes from the fact that the lens's surfaces have the same curvature as the surface of a sphere. This type of lens is widely used in various optical systems due to its simple design and versatility.

The lens's wavelength is 2940 nm, which is in the infrared region of the electromagnetic spectrum. This makes the lens suitable for applications that require the use of infrared light, such as thermal imaging and night vision systems.
