112-5223E 25.4 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens
The 112-5223E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -250 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or to enhance its optical properties.
The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 4 mm, while the center thickness is 3.2 mm. The lens is made of CAF2 (Calcium Fluoride) material, specifically the mal-1963 variant, and is designed to work with a wavelength of 2940 nm.
The 112-5223E is a spherical lens, meaning it has a curved surface that is the same in all meridional sections. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side and a concave surface on the other.
