112-0123E 12.7 mm Dia. x -200mm FL; Uncoated; Plano-Concave Lens

The 112-0123E is a plano-concave lens with a diameter of 12.7 mm and a focal length of -200mm, sourced from EKSMA Optics. This lens is a spherical type, designed with a circular base shape, and is uncoated.

The lens's geometry is meticulously crafted, with a thickness of 3.5 mm at the edge and 3.3 mm at the center. The inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The effective focal length (EFL) is -200mm, which is typical for plano-concave lenses and contributes to the divergence of light rays.

The lens is made from the material n-BK7 Schott, a popular choice in optical applications due to its excellent optical properties. The wavelength for this lens is 546nm.

Please note that this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may affect the lens's performance in certain applications, particularly those requiring high transmission or resistance to environmental conditions.
