LC5919 12.7 mm Dia. CaF2 Plano-Concave Lens; EFL=-18mm Uncoated
The LC5919 is a Plano-Concave Spherical Lens with a diameter of 12.7 mm, sourced from Thorlabs. This lens is designed for use with a wavelength of 588 nm and features an effective focal length (EFL) of -18 mm, making it suitable for applications that require a negative focal length.
The lens is made of Calcium Fluoride (CaF2) with the Mal-1963 material ID, which is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The base shape of the lens is circular, and it has an inner radius of 0 mm and an outer radius of 0 mm. The center thickness of the lens is 2 mm.
Notably, the lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This may affect its performance in certain applications, particularly those that require high transmission or resistance to environmental factors. However, it can be advantageous in applications where cost, simplicity, or specific optical properties are a priority.
