LC4513 25.4 mm Dia. UVFS Plano-Concave Lens; EFL=-75mm Uncoated

The LC4513 is a Plano-Concave Spherical Lens, part of the extensive catalog of optical elements offered by Thorlabs. This lens boasts a diameter of 25.4 mm and a center thickness of 3.5 mm, making it a robust and compact choice for various applications.

The lens's primary feature is its effective focal length (EFL) of -75 mm, which is a negative value, indicating its concave nature. This EFL value is crucial in determining the lens's magnification and field of view in an optical system. The LC4513's concave shape allows it to diverge light, making it ideal for use in applications where beam reduction or dispersion is required.

The lens is made from UVFS material, identified as MAL-1965 in the Material ID. This material is known for its transparency in the ultraviolet, visible, and infrared spectra, making the LC4513 a versatile choice for a wide range of applications.

The LC4513 is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may limit its performance in high-intensity or high-precision applications, it can be advantageous in situations where cost or simplicity is a priority.
