110-5555E 50.8 mm Dia. x 2000 mm FL; Uncoated; Plano-Convex Lens
The 110-5555E is a Plano-Convex lens, a type of spherical lens, with a diameter of 50.8 mm and a focal length of 2000 mm. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens is uncoated, which means it does not have any additional layers to protect it or modify its optical properties.
The lens's geometry is defined by its diameter, thickness, and radii. The diameter is 50.8 mm, and the edge thickness is 4.6 mm, while the center thickness is 5 mm. The inner radius is 0, and the outer radius is also 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 836.5 mm.
The lens is made of CAF2 (Calcium Fluoride), specifically the variant with the Mal-1963 material ID. This material is chosen for its excellent optical properties, including a high transmission rate in the infrared region of the spectrum, specifically at a wavelength of 2940 nm.
