LA4874-405 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=150mm 405nm V-Coat
The LA4874-405 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens features an EFL (Effective Focal Length) of 150.5 mm, which is a crucial factor in determining the lens's magnification and field of view.
The lens's geometry includes a thickness of 2 mm at the edge and 3.2 mm at the center, providing a robust structure that can withstand typical optical setup stresses. The lens's front surface has a radius of curvature of 69 mm, while the back surface is planar, contributing to its Plano-Convex shape.
The LA4874-405 is made from UVFS material with a Mal-1965 Material ID. This material is well-suited for applications involving ultraviolet light, particularly at a wavelength of 587.6 nm. The lens is coated with a V-AR-405 coating on both the front and back surfaces, enhancing its performance in the specified wavelength range.
