LB5864 12.7 mm Dia. CaF2 Double-Convex Lens; EFL=40mm Uncoated
The LB5864 is a 12.7 mm diameter Spherical Lens with a Double-Convex base shape, sourced from Thorlabs. This lens is uncoated and features an effective focal length (EFL) of 40mm, making it suitable for a wide range of optical applications.
The lens's geometry includes a thickness of 2mm at the edge and 3.2mm at the center. The first radius of curvature (R1) is 34.2mm, while the second radius (R2) is -34.2mm, indicating a convex-convex shape. The lens does not have an inner or outer radius.
The LB5864 is made of Calcium Fluoride (CaF2), identified as "caf2 mal-1963" in the Material ID. It is designed to operate at a wavelength of 588nm. The lens's shape is spherical, a common choice for general-purpose optical systems due to its ease of manufacturing and versatility.
Please note that the lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other beneficial optical properties. The absence of a coating on this lens may affect its performance in certain applications, particularly those involving high-intensity light sources or specific wavelength ranges.
