LB5284 25.4 mm Dia. CaF2 Double-Convex Lens; EFL=50mm Uncoated

The LB5284 is a high-quality spherical lens from Thorlabs, featuring a double-convex design with a diameter of 25.4 mm. This lens is made from Calcium Fluoride (CaF2) material, specifically the Mal-1963 variant, which is known for its excellent optical properties.

The lens has an effective focal length (EFL) of 50mm, making it suitable for a wide range of optical applications. The geometry of the lens includes a thickness of 2mm at the edge and 5.9mm at the center, providing a robust structure while maintaining a compact form factor.

The LB5284 does not come with any coating, which is indicated in the 'coating' parameter being an empty object. This means that the lens is uncoated, which may affect its performance in certain applications, particularly those involving high-intensity light sources or specific wavelength ranges.

The lens's design includes an inner radius of 0 and an outer radius of 0, indicating a symmetrical double-convex shape. The radii of curvature for the first and second surfaces are 42.5mm and -42.5mm respectively, which contributes to the lens's overall optical properties.

The lens is designed to operate at a wavelength of 588nm, and the 'weblink status' parameter suggests that it is currently in stock. For more information, users are encouraged to visit the vendor's website through the provided weblink.
