LC4357 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-50mm Uncoated
The LC4357 is a plano-concave lens with a diameter of 12.7 mm, sourced from Thorlabs. This lens is designed for use with a wavelength of 588 nm and is made from UVFS material with the Mal-1965 index. The lens's geometry includes an EFL (Effective Focal Length) of -50 mm, a center thickness of 3.5 mm, and an inner radius of 0 mm. The outer radius is also 0 mm, indicating a flat outer surface. The lens's shape is spherical, and it does not have any coating, as indicated in the item data.
The lens's plano-concave design features one flat surface and one curved surface, which is concave. This design is often used in optical systems to diverge or reduce the diameter of a beam of light. The lens's significant negative EFL indicates that it will spread out light passing through it.
The lens's UVFS material and Mal-1965 index suggest that it is suitable for use in ultraviolet and visible light applications. The lens's uncoated status means that it does not have any additional layers to protect it or modify its optical properties.
