LB4913-UV 25.4 mm Dia. UVFS Double-Convex Lens; EFL=125mm 245-400nm
The LB4913-UV is a double-convex lens with a diameter of 25.4 mm, designed for use in the ultraviolet spectrum with a wavelength of 588 nm. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
The lens features a focal length (EFL) of 125 mm, making it suitable for a wide range of applications that require precise focusing of ultraviolet light. The double-convex design, with radii of curvature of 114.5 mm for both the front and back surfaces, ensures efficient light transmission and minimal distortion.
The lens is made from UVFS, a material specifically designed for use in the ultraviolet spectrum. This material, identified by the Material ID "uvfs mal- 1965", provides excellent transparency and durability in UV applications.
The LB4913-UV is coated with Tho UVFS UV BAR on both the front and back surfaces. This coating enhances the lens's performance in the UV spectrum, reducing reflection and increasing transmission.
The lens has a thickness of 2 mm at the edge and 3.4 mm at the center, providing robustness and stability. The circular geometry of the lens allows for easy integration into various optical systems.
