LC4291 8 mm Dia. UVFS Plano-Concave Lens; EFL=-12mm Uncoated
The LC4291 is an 8 mm diameter Plano-Concave Lens, part of Thorlabs' extensive catalog of optical elements. This lens is designed for use in ultraviolet-fused silica (UVFS), a material known for its high transparency in the ultraviolet spectrum. The lens's base shape is circular, and it features a concave shape with a center thickness of 2 mm.
The effective focal length (EFL) of the LC4291 is -12 mm, indicating that it is a diverging lens. This means that it spreads out light rays, making it suitable for applications such as beam expansion or collimation. The lens's inner and outer radii are both 0, and its shape is spherical.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still suitable for many applications, particularly those where cost-effectiveness is a priority. The lens is designed to work with a wavelength of 588 nm.
